Nice weekend getaway!

8.0

The location and views were absolutely stunning! The vibe was amazing, and the rooms were spacious and very comfortable. The food was just okay, but the service and staff were outstanding—special shoutout to Annie at the beach bar and Gar for making the experience even better!

Perfect for multi generational family trip

10.0

We were there to celebrate my husband’s 40th birthday. We had our sons with us, 6, 7, and 11 years old. My in-laws also came with us (60s). It went great. There was something for everyone. Beach, pools, games, restaurants, bars, bikes, jet skis, etc. Everything was family friendly, and the resort was really nice.

Little things

10.0

Tv issues: not enough apps. No ABC. Staff was very courteous but many had trouble understanding English. It would be great if you had a few Pickleball courts.

Utterly disappointed

2.0

This might have been a good place to visit about 10-15 years ago, but our visit was anything but enjoyable. Our room was borderline filthy, and generally, everything seems neglected, tired, desperately needing deep cleaning, repair, or a full rehab. Whether at the restaurant, the burger joint, or the beach bar, the food is simply terrible, and if that’s at all possible, the service is even worse. Most employees have that distinct look on their face that clearly tells you that they’d rather be anywhere else doing anything else. The very first time we sat at the restaurant, we waited 30 minutes without anyone coming by to greet us and offer menus. I finally went inside to talk to someone, wondering if we actually needed to order at the bar. I was told that someone would come out and… you guessed it, no one did. Waited another 20 minutes, went back inside, and… was told that all we can get is coffee, since by then they had closed for breakfast. The next day we sat at the beach bar and ordered pizza. Not only did it taste worse that the frozen pizza you get at the grocery store, but it was so undercooked, the cheese hadn’t even melted and the dough tasted raw. I ate one slice and gave up. When we got the check and the waiter asks if I needed a box, I told him that I don’t need one, explaining why. There was no acknowledgment and you could tell that he gave zero sh*ts. As I had already submitted some feedback, the F&B manager reached via email to invite us to give them another try but after two consecutive failures, I told her we’ll be better off eating off the property. And, I was right. Separately, we booked through a third party OTA and we never consented to the property’s privacy policy. That didn’t prevent them from sharing my PII with at least three other partners, all sending emails within 25 hours of checking out. Multiple emails to the property went unanswered. There seem to be plenty of guests who like this place, but unless your expectations are really low, spare yourself the disappointment and book elsewhere. There is nothing luxurious about this place.

lovely property

8.0

Beautiful property with large ocean facing rooms and good size balcony. Along a long stretch of the coast with a small swimmable beach that could use some improvement. Numerous pools spread out. The marketplace was cute but limited. Very clean was self parking. High end prices, come prepared.
