Hertz has vehicles available to seat 6 and you can rent right at the pier. Go to hertz.sxmrentacar.com and choose arriving by cruiseship.
The very first time we went to St. Maarten was by cruiseship and rented a car and drove around both dutch and french side. Traffic will depend on how many ships are in port. Do you know what day of the week you will be there?
