We stayed there summer 2017. I wouldn't have characterized it as crazy crowded, but the chairs around the pool were all taken and there were a lot of people in the pool. Lines and waits for the slides. Felt more like a Disney water park than a resort. We didn't have any trouble renting paddle boards, but the ocean was too rough to do it comfortably.
The one thing that wasn't crowded was the SCUBA diving lesson. They have a training pool at the resort and then they take you out in the ocean. My son wanted to do it, and there was one other parent and his kid signed up. The other kid couldn't ever get his mask to seat properly, so they couldn't do the ocean dive. So, my son got essentially a private dive in the ocean. He still talks about it to this day and now has his diving certification. That lesson was some of the best money I ever spent.
The spa there is amazing. One of the best I've ever been to.
