I'm in the very early stages of planning a trip to Dominica next winter (Feb 2015) & am finding the best/easiest way to get there is thru San Juan. I'm planning to overnight there on the way down so no worry about customs, etc. My question is the return trip--if we can leave Dominica & arrive in San Juan before continuing on to Dulles, how much time do I need? I haven't made the flight reservations yet as I'm concerned about this. I realize it's going to be a very long day of travel but if we can do it all in one day, that's what I'm inclined to do. May be a mistake? If anyone has done this, let me know your feelings either way. We'll be coming home on a Friday & looks like we have several options for flights back. From what I've read, I think I'll stay away from LIAT.
