Hi BeachParty,
We stayed at the Ron Jon for two nights before our cruise, so hopefully I can help. The regular pool remains open after 5pm, but the Lazy River and Water Slide shut down at that time every day. (I don't know if it's because it gives them time to clean and dinsinfect everything before dark, or if after an afternoon of adult beverages they figure enough for the day

It did seem early to us too. We ended up heading down to the beach via their tram, and went swimming in the ocean instead. It was really fun.
As far as hauling luggage, we had to do that. We arrived at 11pm and had to ring a bell for access to the main lobby, which you could access if you had your room key. I did like that security feature. But other than the help at the desk, who were pleasant, there were no bellhops in sight. When we left Saturday morning we didn't see any either, but in Ron Jon's defense we had already decided to wheel the bags out ourselves and never called for help from the desk. We were in the main building, and it wasn't far to bring them to the room, and of course there are elevators. I am looking at a map they provided when we checked in, but the various buildings are not labeled, just the pool, restaurants etc.
We really liked our stay at RonJons-we had rental car and planned to Kennedy Space Center on Friday, but ditched that idea and stayed by the pool most of the day. They had entertainment, and bar area poolside where you could also order food and buy ice cream.
We rented a studio room for 4 of us, and although it was nice and clean, it was small. The bathroom, however, was the size of the sitting room area. I did pick this type of room on purpose though, so we wouldn't go from a huge hotel room to the ship's cabin which might feel a lot smaller.
The big negative for us was we had a very loud family next door to us, and the rooms were connecting and the soundproofing at the door is not so good. The Dad was yelling and the kids were talking back and it all went on almost to midnight. Not cool. My daughters were horrified. If they acted like that I swear I would never take them on vacation again.
We checked into getting a shuttle from Ron Jons to the port and getting rid of the rental early, but it didn't sound too promising so we stuck with our original plan.
Have fun!
Kathy
