We are a group of 5 who will be returning to Paris from Normandy, and dropping car off near CDG.
We will spend our final night in Paris before returning home next day at 10am
Would like recommendations for hotels under $200 for the night convenient to sights and airport
We wil need 3 rooms , one of which is a single, if offered
Any suggestions?

This is tricky as CDG is not convenient to sights and, allowing time for security, you have a fairly early flight. What time are you returning the car? It might be best to drop the car take the RER/Metro into Paris for the day and return that night to an airport hotel.

Yes, upon further consideration I think that may be the better choice
We could take the train into Paris for the evening
I just hate to stay at airport hotels
Price line had some good rates Hyatt for $115
Thanks

I agree. It doesn't really make any difference for one night about the hotel to me, before you get up early to go to the airport. You will be very glad the next morning, I bet.

Plus, if you're coming from Normandy, it makes no sense to drive to the other side of Paris just to drop a car off at the airport. If you're worried about dropping it off IN Paris (and there's really no reason to be), then drop it in Versailles or somewhere just west of Paris where you can hop a train or RER back to the city. Or leave it in Caen or Bayeux and take the train.

As for hotels, there's a million threads here about hotels in Paris at all budget levels.
