Enjoy your first trip. since you will be staying on SXM for only one week, may i suggest scrapping your plans for the day trip to Anguilla. With over thirty beaches on Saint Martin, why waste a day going over to Anguilla? When we did the Anguilla thing years ago, we were not impressed at all....except for looking across the bay and seeing the mountains of Saint Martin. You will find seven days you won't get to do even a third of the things you want to do. LOL Sand Gravity takes over.
