Getting to the Caribbean s not an easy feat. Especially from the west coast. I already had a trip planned to be in MCO in March and added on a flight to get down. SInce I was going to be on a DL ticket, that meant flying back to ATL then down to SJU. I'll be taking a ferry over to Tortola and then fly back to SJU.
Most airlines are on a set schedule of Fri/Sat/Sun/Mon service with nothing inbetween depending upon where you want to go.
