We rented the cabana when we were on the Harmony in September. Our cabana was located next to the wave pool area, so a bit of a distance from the slides. However, it was a nice area.
My family consisted of me, DH, 13 year old DS, and 8 year old DS. It was perfect for us because my DH is not a water park person and this gave him a spot to relax. It was nice to have a button to press anytime we needed anything and our attendant appeared to help us. I also liked to peace of mind of the locker to put our stuff when we all were not there. The towels were in the cabana, so we didn't have to bring them from the ship. We had 6 bottles of water in a cooler. Our attendant brought us food at least 3 times. At the end of the day, she dropped off fresh fruit skewers. We had the drink package, so she also brought us virgin daiquiris for the kids and beer for the adults. The cabana manager stopped by to introduce himself and he wanted to make sure that we had everything we needed.
For our Harmony cruise, I think I paid $370 and we thought it was worth it. For our Mariner cruise next year, the price really dropped to $299. Compared to
DCL prices, we thought we got a bargain! We've rented cabanas at WDW and our local water park and we thought the ones at Coco Cay beat those experiences.
