Yes you can definitely see the waterpark from a waterpark cabana as you're in the waterpark. Our cabana was #50 just a few steps from the big slide. We had a perfect location for our grandkids and it was well worth the $'s.
We've also had a change of flight times in SJU. We were "first" off the ship into a taxi checked in we were also 1st class and made our 9:45am flight with time to spare.
You'll be fine and don't stress. And remember if you have a concierge they can make sure you're first off like they did for us...we were walked off. Just ask for help if you need it. You'll be surprised at how accommodating RCI can be when asked onboard.
Your cabin steward will help (a lot of people don't realize they help with this all the time) or they will call for someone that will. Just bring everything you might need.
Firestick and remote, an HDMI cable and just to be on the safe side a universal remote that will work with Samsung TV's. This way you'll be prepared...best of luck.
I'll suggest Cruise Control...worked great for our group of 6 round trip. If it's just two of you and you're a Costco member check their rates online for a rental.
Our first Royal Up (post covid) was $350 pp going from a JS to the OS 7 nights on Navigator. Money well spent as my JS pricing was really low and booked when the sailing opened.
Nice to know and I agree if you're just changing locations and there's cabins available a call to RCI wouldn't hurt. I certainly would do this before boarding .
This is not necessarily true about suite pricing as other factors come into play. I'm not asking for sky class benefits but including internet shouldn't be that big of a deal.
No hotel shuttles but I can recommend Auberge Place d' Armes. We stayed there pre-cruise and took a taxi. Great hotel and perfect location. Also check Royal Palace Hotel also good location but again you'll need a taxi.
