I am from the Bay Area, and I plan to use the SJC-JAX fare with some friends and stay three nights at the Sheraton Vistana Resort in St. Augustine. What it this place like? Are the beaches cool. Our ages are 18-20. Will this be enjoyable. We can do this Sep 15-18. Also there is an option to West Palm Beach, and staying at the Shetaron Port St Lucia Resort. The fares for this are dying,and we would have to take Sep 30-Oct 3. What would be best for us, could you please explain what these places are like? I appreciate any input, as I am trying to plan this now, and buy within a day.

Thanks
