I will not recommand Grande Vista.
We just came back last week. The resort is large and a good location, look great from outside.
But we had an awful experience there. We got roaches problem in our room. I understand that roaches can be common in Florida. I won't complain if just one or two. But they are so many. They are everywhere in the kichen and bathroom. We asked housekeeping to come and spray every night and it was still useless. I tried to use dish washer before I use any of those dishes. However, on the 4th night, I found them in the washer too, not very long after the machine's job is done. And I also found one in the refrigerator.
We asked for exchange for another room. But the dish washer didn't work well in the new unit. And we have spend extra time to pack and unpack our staff.
We talked to the people who stayed there. Some of they seems ok and didn't run into the bug problem. I guess it depends on your luck then.
