9.2/10 Wonderful! (1,828 reviews)
Staff was great, but rooms and amenities were incredibly dated. The bathroom had no ventilation, a very old shower, and mediocre product options. The rooms were very bare bones and not warm or inviting. There was nothing all that special about this property and certainty not worth the nightly rate.

Lovely property. Very well maintained and taken care of. The option of pool or beach is a plus. Although we didn’t utilize the activities available each day.. it seemed very family friendly. Definitely will be back but hopefully reserve a bigger room or suite. Charming outdoor seating on the huge lawn but mostly in the sun. An indoor lobby with some comfy seating would be great.
