some fairly recent exterior shots, pool and info:

After looking at these shots I'm reasonably sure that if another hurricane comes through the Orlando area, the THVs will be evacuated... just too much glass. Not that I'd avoid staying here, I love summer in FL and love the campy feeling even more, but it is a thought to consider in case anyone's staying during hurricane season. Watch the weather and be prepared to pack.
