My daughter and six of her friends (all college seniors) just spent last week there at GV on Spring Break, and I got them a fantastic unit in the 81 building, overlooking main pool and beach area. All said it was the best Spring Break they ever had, if not one of the best vacations ever. The weather was sunny, clear, and warm every single day-----temps in low-to-mid 80's----in other words, perfect.
They are not partyers, but enjoyed the pools, beach area, volley ball, etc......and really enjoyed being in that location. Personal opinion is you can't get a better bldg than that, unless you want peace and quiet somewhere along the remote area of the lake.
The kids were flabbergasted at how nice the resort was. Some of them had never experienced the Marriott timeshare brand before. A week in Orlando on college Spring Break, are you kidding? I wish I had been so lucky.
