We flew yesterday from Saint Maarten. Thanks to the boards here we knew not to go to the airport early for our 4:30 flight. We tried to get a day room but there were none available. The Holland House will let you use their facilities and even lock your luggage but if we went to the beach I would want to take a shower. When we picked up our luggage we asked our porter to see if he could find a driver to take us around the island until 1:30pm. We had a lovely morning touring the island, seeing lovely beaches and lunch in Margot. At 1:30 she took us to the airport and the line was wrapped around the building. I asked our driver to take us for another hour. We returned at 2:30pm. We only had to wait outside for 1/2 hour and another 1/2 inside.
Outside if you had an earlier flight, the attendents would allow them to jump the line.
It was a madhouse , you would led into one huge room.
I would try to minumize your time at the airport.
