Originally got a one bedroom villa and got a free upgrade to a two bedroom which was perfect. The villa was super clean, easy access, washer/dryer, kitchen fully stored with pots, pans, utensils, cups, and plates. They had enough towels for our entire stay, and even had beach towels as well. They had everything that you needed. I didn’t need to call the front desk for anything my entire stay. I loved that place and the size of the villa was perfect for the two of us and maybe more. Definitely will come back if I’m ever back in Orlando.

Super easy check in, friendly staff. Alex gave me all the info that I needed. House keepers works hard. Love the place. Definitely will come back. Water park was awesome and there's no need to go out if you don't want to. There's food for sale, drinks, snacks, acai, etc
