Congratulations on your upcoming TN wedding! Most important thing is relax and enjoy the island, especially after the stress of preparing for and then completing the festivities of your wedding day. As others have mentioned don't try to do too much on your first trip to SXM - believe me you will return. In your travels around the island, you should buy some special item, be it jewelry, artwork, or even a simple souvenir to remind you of your honeymoon on the "Friendly Island" while you continue your lives together.
