What I've heard most often here on the DIS are people reporting Roaches, but when asked to describe the bugs they are actually the Palmetto bugs that are all over Florida and impossible to keep out. Palmetto bugs may look like a larger roach, but they are flying bugs which may "visit" your room, but aren't likely to be taking residence there and actually infesting the area. Since most pest control utilizes sprays which create barriers around entrances (windows, doors, etc), It is much more difficult to protect against flying bugs who can easily bypass the sprayed surfaces.
I honestly wouldn't worry about a roach problem at this resort. I've stayed there multiple times and never seen any signs of infestations. There have also been numerous DIS members who have stayed there over the past several years, and only a few have reported anything roach-like, which several have been the a fore mentioned Palmetto bugs.
