Freedom of the Seas RCCL next month. First cruise since 2010 have questions...

Taking our first cruise since 2010. It is on RC Freedom of the Seas December, 2024.

Wife and I, both 60s, her brother, 60, and his daughter (our niece), 14.

Any tips for this specific cruise/ship? Things to avoid or must see?

Oddly specific questions:

-Is it worth it to join Crown and Anchor for one cruise?

-I drink water 99.99% of the time and have no interest in drinking anything else. Do they have water bottle refill stations around the ship? I just don’t want to get stuck paying for bottled water every day.
