I would recommend Big Pine Key. It's close to the main building and pools. We were in Boca Chica, and while we had a MK view (got upgraded from a lagoon view), I found the building kind of an annoyingly long walk from most things at the resort. When it was storming hard/pouring for 2 hours on 2 separate days, we were stuck in the room because the walk to the main building was mostly all undercover. I didn't like that.
