We will be in SXM for Christmas we arrive that day, we will be in St Barts for New Year’s Eve . As everyone has said I hope you have your hotel/villa reservations. We made ours back in January for both SXM and St Barts. As for transportation we use the ferry from Phillipsburg, it’s a short ride and the captain and crew are a great group of folks. New Year’s Eve is a great time in St Barts, there is a lot of activities around the harbor and a huge fireworks display at midnight , the party then continues at Le Select till the morning.
