Looking for a kid friendly vacation spot with water slides and ocean

Recently started traveling more with our kids, we have traditionally camped around our area, our kids are very outdoorsy. We went to Myrtle Beach and stayed at Crown Reef Resort and Waterpark and we had a great time. Our girls were obsessed with the pools and water slides but the ocean was a little rough for them, they’re 4 and 6, and they’ve grown up on a lake so not as used to larger waves.

Looking for something similar, or wondering if that’s where we should back to. Doesn’t matter if it’s all inclusive or not (actually there we had our own kitchen and made all our meals), but separate sleeping areas would be ideal. Not a deal breaker if not. We just would like a family friendly location with calmer ocean and water slides on site. No Disney as we have that planned in a couple of years. Would prefer to stay on the east coast/Caribbean but will fly. Looking to go end of June/early July!

Thank you for any help!
