There is a chance that the 10:00 am RTFF will not be running, especially if it is in the low season. This happened to us twice. On one occasion, We called RTFF the day prior too our return they told us it would be running but the next day it wasn't. We missed our flight in STT and stayed at Best Western Caribe across from the airport. The next time we took first ferry, had breakfast at Glady's, lunch at BW Emarald Beach and then on to STT, much less stress. I had never considered flying from EIS to STT, something to consider.
