Glad to help out. If you choose St. Bart's, here's a few tips to consider. You can still fly into SXM and take a taxi to the port in Philipsburg. You can take the Great Bay Express to St. Bart's which is about a 40 minute ferry boat ride. They will take any luggage you have, and they even give you a small bottle of water. But, the ride can be a bit 'choppy' depending upon the seas so bring some peppermints along if you get a queasy stomach. Next, you can get a rental car at a decent rate delivered right to you at the port in Gustavia. Never take a taxi on St. Bart's (they're hard to find and outrageously expensive). I would suggest going the AirBnB route (or Vrbo) to secure your lodging. Most of the hotels charge prices that are way too high ($1,000 a night and higher is not uncommon here). And, be sure the place that you select has parking for their guests. Finally, invest in a nice beach umbrella and some good beach towels and a small travel cooler before you go. Most of the beaches have no facilities, and the ones that do are very high priced. Bringing your drinks and snacks is a smart move and will save you a few euros. Euros are the standard currency here, so get some in advance in addition to using a credit card. Personally, I still prefer St. Martin but St. Bart's is beautiful and worth a try as an alternate destination.
