As I mentioned in my trip report, we did go to the pool at The Flamingo. I think it was posted that there was a $15.00 charge but they never asked for any money, just a Harrah's room key.
On our next trip(August) we will be staying at Harrahs and plan to use the Caeasars Pool, rent a cabana and schedule a massage.
I was told that we could do this, even tho we are at Harrah's and from what everyone else has said, it should wokr out ok. Now all I have to do is call and get is all set up.
