St. Thomas vs. St. Lucia vs. ???

I've heard that St. Thomas has tons of all-inclusive resorts. I'm not sure about the resorts in St. Croix USVI, but I know the culture aspect is definitely more prevalent than St. Thomas which can be very crowded and touristy. Antigua is another one worth looking into. They have a lot of different cool activities, 365 beaches or so they say, and plenty of culture. It's a popular destination, so typically there are direct flights to Antigua. I don't know about resorts there though.

I know St. Thomas was hit by Irma last year. I would check to see how things are progressing on that island: https://www.npr.org/2018/02/02/580448399/visitors-slowly-returning-to-virgin-islands-after-hurricanes-destruction. Technically hurricane season runs from June to November. It's probably unlikely to see a hurricane in November though...but, you never know.

Going to St Thomas I did stay for 5 days & had plenty to do, you could visit the different beaches or even take a ferry to St John (only 20 mins away) to do island tours. When I went I stayed with my aunt so I’m sorry I can’t really help with finding resorts but it was a beautiful place if you are looking for relaxing activity, scenery & nightlife.
