For me, the perfect stay-cation place is Plantation Bay. July is the perfect month to stay outdoor. It has the right amount of sun and clouds not to burn your skin too much. The resort has a lot of recreational things you can do too. When I saw stand-up paddle boards, I just had to try them. You can kayak, bicycle, and use their game room. The game room has dart, pool table, foosball, and table tennis.
I had so much fun that I need to re-energize. Excuse me while I get inside my cave to hibernate. hehe :)
