You have received sound advice from others. You will likely catch a main flight into SXM and then a quick, short hop to Saba. I've know many scuba enthusiasts that only know Sint Maarten as a stopover to Saba. Casinos, incredible gourmet, cuisine, white sandy beaches, Caribbean shopping, that's Sint Maarten/ Saint Martin. Quiet, good diving experience, local small food bar/restaurants, hiking, that's Saba. We are returning to our long time (35+ years SXM) vacation love later this year.
