We'll have a pretty full day available when our cruise docks in Phillipsburg. Only one ship in port that day so should not be too busy. We've been to SXM once before and took a cab, but this time with a 8-5 window (onboard at 6) we're planning on renting a car and doing some touring. We were thinking about heading to GC for and early brunch/breakfast, then maybe hike to HB for a couple of hours, lunch at Anse Marcel and then the afternoon at Club O Beach, leaving about 4. Too much?
