I wish I'd kept mine (just checked out 2 weeks ago)....I called the hotel before I left and asked them to fax me one. It wasn't the best map, but I knew the layout before I got there.
We stayed at the Grande Vista last Oct. It was wonderful, of course I can't remember the building number. I do remember the the newer (nicer) units are in the back. They recently built a new pool and I think there are new units surrounding it. The only benifit of being in the front is you are much closer to the main building with the store, snack shop play area etc. Have a great time!! Let me know if you need more info. We are going again Oct 9-17 (weather permitting!) this time we are staying at Marriotts Horizons.
