Springtime in Paris

Departures: May 5, 12, 19 and June 9

4 days for $129 per person

Paris in the Springtime was, is and always will be, something rather special. Why not experience it for yourself with this excellent break for four days? This attractive city has something to offer everyone and with prices at just $129. It's great value too.

Your break begins with executive coach transfer (中转) from regional (各地的) pick­up points and travel to Paris is via cross­channel ferry (渡船), arriving at your hotel in the evening. The Ibis is an excellent quality hotel with private facilities in all rooms: satellite TV, radio, telephone and alarm clock. It has a bar and a restaurant and is situated about two miles south of Notre Dame enabling you to explore Paris with ease.

The following day, after continental breakfast (included), the coach takes you on a comprehensive sightseeing tour of the city, during which you will see the Eiffel Tower, Champs Elysees, L'Arc de Triomphe, the Louvre, in fact almost every famous landmark you will ever have heard of. You then leave Paris and take a short drive to the magnificent Palace of Versailles, the home of Louis XIV. The tour ends mid­afternoon back in Paris where you will have the remainder of the day at your leisure. In the evening there is a ‘Paris By Night’ tour showing you the beautiful buildings with bright lights.

Day three takes you to Montmartre, perhaps the most picturesque quarter of Paris and home of the Sacre Coeur and the Moulin Rouge. In the afternoon you are free to explore this beautiful city as you wish, perhaps a pleasure voyage on the River Seine, wander around the picturesque gardens or look through among the antique shops (古玩店). In the evening you will have the opportunity to visit the best night­club in the city, the splendid Patin. On the final day it's back to the UK via channel ferry.

Included in the price of $129 per person:

* Return executive coach travel to Paris;

* Return ferry crossings;

* Three nights accommodation in a twin bedded room in a Central Paris hotel with private facilities;

* Continental breakfast during your stay;

* Guided sightseeing tour of “Paris By Day” and “Paris By Night”;
