Where can I find really good, unknown deals on Paris hotels and airline tickets online?

I'm assuming you are American. Here is a tactic I use when looking for deals for myself or clients. Do a Google search for "hotel paris site:.fr" (without the quote marks). This will return ONLY sites with the dot-fr suffix. In other words, only FRENCH sites. Often you will find hotels and booking engines that you wouldn't find otherwise. In place of hotel, you could use French words like logement, hebergement, appartement, sous-location (sublet). Here's a French hotel chain with many sub brands: http://www.accorhotels.com Also: http://www.hotelformule1.com Formule1 is their budget brand. Good luck.

If you are a student (and have a valid student ID), you can go through statravel.com. They have amazing deals on transportation, lodging, etc. AND they also have prepackaged travel plans that you can consider. Many campus centers at larger universities include STA Travel travel agencies, so you may be able to talk to a representative in person.

http://roachenterprise.com. they have everything you need to travel anywhere in the world. you can buy airline tickets really cheap, and even book car rentals and hotel reservations for wherever you are going.

Paris is the single most popular tourist destination in the world. It is a bit of wishful thinking to believe there is anything unknown about travel there. Getting the best deals on a trip to Paris is a matter of constantly checking airfares, a willingness to be flexible as to the time of your trip and recognizing that you don't need a hotel that has cable TV, elevators, and minibar. Check out the hotels on Eurocheapo (http://www.eurocheapo.com/paris/) and consider a hostel.
