For the many that travel through Paris' Charles de Gaulle airport at any one busy time and require accommodation, there can't be one too many hotels in the area. New hotels are being built and furnished as we speak in Roissy-en-France; a testament to how busy this place gets many times a year. There are currently at least thirty hotels servicing the area, but demand exceeds supply and that theory of Economics proffers to provide the solution.
The downside to staying outside of the CDG (Charles de Gaulle) airport terminals is the necessity of transporting luggage to and fro. Free shuttle buses between hotels and airport pick up passengers every half an hour. These stop on the top ramp of Terminal Two and if you miss one sign directing you to the place, don't worry there are enough signs in all three terminals. And then there are airport lockers for those who can't be bothered to lug suitcases around. Taxis are a handier option and cost around twenty Euros to hotels in the airport vicinity.
Mercure Hotel has a pleasant, inviting facade. The hotel lobby is large and commodious. Reception staff members are friendly and helpful. My room was simple with the usual hotel furnishings of a TV, a small fridge, seats, a table, and more importantly, a large bed. The room was smallish but served the purpose of accommodating me comfortably for the night. It was quiet and free from any and all airport-related noise. Across the lobby is the hotel bar and restaurant, which offers set menus and a small buffet selection for breakfast, lunch and dinner. Free internet access is available in the lobby. Expect to pay around two hundred dollars for a night's accommodation, but do watch out for specials as you may end up paying only half of that amount. I booked using a mystery hotel deal, paid less than half the full price and was glad to have mystery picked Mercure Hotel instead of one of the others.
