Tour
A week-long tour to Paris (airfare, insurance, accommodation in a two-star hotel, breakfast, sightseeing tour) will cost 525 euros. A visa will be issued for 35 euros.
Transport
A car in Paris is not particularly relevant: there are traffic jams, and parking is difficult. A car will be useful only if you plan long excursions outside the city. Otherwise, it is better to explore Paris on foot or by metro.
Metro. The fare resembles our payment system: a single ticket costs 1.3 euros, a booklet of ten tickets costs 10 euros. Even better is to get a "Carte Orange" - a weekly metro pass for 32 euros. Let's focus on the main differences between the Paris metro and the one back home. While the train is moving, you can walk from car to car, like on a commuter train. The doors open manually, both from outside and inside. The distances between stations are very short (300-400 m). From a metro platform you can go only in one direction, so to go in the opposite direction, you have to use a passage to the other platform.
Unquestionable advantages of the Paris version: there is no oncoming passenger flow in the metro, and instead of ads, the cars have large train route diagrams visible from anywhere. The downsides are the rather long walks from platform to platform through untidy, gloomy passages. For orientation, remember the number of the metro line you need (they are all numbered) and the names of its terminal stations. When transferring, follow signs with the number of the line you need and the names of the terminal stations.
Total: 32 euros.
Taxi. You can only take a taxi at special stands. You can also call a taxi by phone from the hotel. Hailing a car on the street is practically hopeless. But if you follow the established rules, you'll get a new perspective on a familiar service: first you get into the car, conveniently place your luggage, and only then say where you need to go. Exactly in that order.
Total: about 70 euros for two or three trips around the city.
Restaurants
A continental breakfast, as elsewhere in Europe, is modest and concise: croissant, a piece of butter, a pack of jam, cheese, cereal, tea, coffee, milk. A modest lunch at a café costs around 12 euros. You might come across an offer promising six oysters and a glass of wine for five euros. Such a set is clearly not enough for lunch, but it is just right for an afternoon snack or second breakfast. Those who are tired of menus entirely in French and waiters who respond sluggishly to questions in English can be advised to visit a Chinese eatery. The food there is traditionally cheap and tasty (seven to eight euros).
Completing the international picture are ubiquitous hamburgers with Coca-Cola (three euros). Beer in Paris is outrageously expensive - about five euros for a half-liter mug. But what you won't mind spending money on is the incredibly delicious Berthillon ice cream at 1.5 euros per scoop.
Total: moderately modest international lunches and dinners will cost 150-180 euros.
Museums
Admission to city museums costs approximately six to seven euros (visiting Notre-Dame - 6.1 euros, climbing the Eiffel Tower - 10.5 euros). At this point we should mention the famous museum card (a multi-entry ticket to Paris museums). It costs 15 euros for one day, 30 euros for three days. Skeptics believe that the card pays off only if you visit at least three museums a day, which is unrealistic and simply exhausting. However, one should not forget that the card applies not only to major museums but also to attractions such as Notre-Dame, the Arc de Triomphe, the Arche de la Défense, and others. So if you plan in advance a rough cultural enrichment itinerary with three or four attractions, the museum card will pay off on the first day. Another advantage: the museum card's coverage extends beyond Paris. You can visit Versailles, Fontainebleau, and the museums of Île-de-France.
You can buy the magic card at the ticket office of any museum on the list, or at the metro (don't forget to bring a small photo to attach to the card). Warning: the card is not valid in private museums or at the Eiffel Tower. By the way, be prepared to stand in a total of four lines to get into the two huge elevators that take tourists up and down.
Total: about 60 euros.
Entertainment
A boat ride on the yellow, swirling Seine will cost nine euros. A full day at Aquaboulevard costs the same: the largest water park in Europe is located right in the center of Paris. Another not-quite-Parisian entertainment is a trip to Disneyland (the trip from the French capital takes just under an hour). An adult ticket for the whole day costs about 36 euros. A ticket to the evening show at the Moulin Rouge cabaret, including dinner and dancing before the show, will cost 72 euros.
Total: 126 euros.
Shopping
In short, fashionable clothes in Paris boutiques cost half as much as in our capital's shops. If you have no spare money but have free time, it's worth visiting the Tati stores. With persistence and patience, you can pick up very nice, quality items from last year's collections of well-known brands. And for serious shopping, it's better to visit Paris in July, a month avoided by typical tourists and full of widespread discounts and sales.
Perfume. If you haven't been talked into a fragrant shopping spree at the Fragonard perfume museum store, then one evening you can combine a walk along the Champs-Élysées with a visit to a huge perfume store of the Sephora chain, especially since it's open until 11 p.m. True, it has been established that the enormous selection of perfumes, eau de toilette, and other fragrances can cause euphoria and, with equal probability, plunge you into despondency due to the impossibility of settling on something in this abundance. They say tourists armed with lists of specific necessary purchases feel more comfortable.
Souvenirs. Hand on heart, it must be said that typical tourist souvenirs in Paris are incredibly monotonous and expensive. In 99 cases out of 100, they are images of the Eiffel Tower on T-shirts, caps, other items of clothing and household items, or as keychains. Purchases at the famous flea markets are far more interesting and educational, where completely unexpected and strange things are found. For example, signed greeting cards from the early 20th century.
Miscellaneous
Tips. Waiters are left 5-10% of the bill amount, and the same can be given to a taxi driver. Tips for hotel staff - bellboy, maid - amount to about one euro.
Toilet. Automatic stalls, clean and tidy, operate until ten in the evening, the fee is 0.3-0.4 euros. At a later time, you can only rely on your own ingenuity. Notably, in some cafes and restaurants you have to pay to use the toilet.
Summing up
With moderate demands and high activity, a week in Paris will cost about 900 euros (560 euros - the cost of the tour and visa, 340 euros - expenses).
