"The facility is beautiful, clean and well maintained. The staff are amazing, warm, friendly and helpful. The resort fee gives you access to rent various things which helped us to have a nice beach day at a beach recommended by the staff. The infinity pool is beautiful and located near the bar, which is nice! There are actually multiple pools on property. We loved our stay and will be back!"
