First cruise and it's solo!

Hi friends! I'll be turning 55 in May and I haven't taken a vacation since right before I turned 50 (then I took a solo trip to Puerto Rico). This time I'm going on a short cruise to the Bahamas on Royal Caribbean Jewel of the Seas in early September. I think I got a really good deal and am excited for my trip. Just looking for any advice or suggestions or whatever 😁 from solo cruisers, cruisers who have been on Jewel of the Seas or anyone else who'd like to comment. Also, any must bring lists? Thanks!
