Flying with a layover in Paris for 18 hours was exciting, especially with a crowd of friends. You get to learn the map, the REV schedules, and definitely, the witness-or-victim-of-a-crime paranoia almost inevitably haunting backpacks and purse owners in town . Yet, 11 months later, I have to go back alone, for another (this time a 24 hr) layover, along with a 6-7 kg backpack, containing my precious laptop. I have no problem sleeping at the airport for a night, however waiting the day there would be a pity. A friend of mine mentioned the Formule1 hotel chain, where a single room would cost 30 euro (No problem, I thought, if I can leave my backpack, take a walk around the city and get back for a good night sleep). The last time we (friends and I) shared a room at b&b, but the prices were great for a group of people, not a single. Our group took a shuttle from CDG to the hotel and then another one to the REV station for going downtown.
This time, I don't know anything about the reliability of the Formule 1 hotels and their closeness to CDG (respectively, to cheap means of transportation). Has anybody happened to use their service? Can you, please, tell me if they're approachable by airport shuttles and/or metro stations? Thank you in advance!

P.S. If you can think of a better way I can possibly resolve the heavy luggage + overnight stay issue, please let me know. The layover time is between 11 am on the 28th and 9 am, the 29th of June. Thanks again.
