Re: Paris Pool Villa/Cabana

My wife and I along with some friends will be there in August (a total of 7).
We have been looking at the cabanas and pools for awhile, but decided against it. The prices you quoted are old (Paris has not updated its website). A few months ago, cabanas and villas were $200/$250 Monday through Thursday, and did not include any booze. They are now $300/$400 (more Fri - Sun), and they throw in your choice of bottle.
I am definitely a pool person, and was seriously considering the cabana. With the 18% automatic gratuity, even with 7 of us it would be $50 a piece just to get in the door, not to mention any other food, etc. we ordered.
This was a deal breaker to some in my party, so we'll just go and sit in the chairs with the commoners.
Just wanted to let you know that the prices have increased. Enjoy your trip!
I could see if there was a maitre d who should be tipped if he gave you a preferential villa, but this gratuity smacks of being the same as a resort fee.
