We stayed there several years ago on a SkyAuction bid ($199/wk 2bdrm). It was a nice resort and we enjoyed our stay. However, we probably wouldn't go back at it is a bit of a drive back and forth to the parks, 30 mins each way depending on traffic. Not so bad in the morning but at the end of a long day, it seemed like a long way.
While we didn't see any gators or had our brains eaten, Summer Bay's true claim to "fame" is they experienced a sinkhole that swallowed a couple of their buildings (just google "Summer Bay Sinkhole Clermont"). Supposedly rebuilt but...
