I will be down solo for the 4th time on 3/22--you will love it! As long as you keep a smile on your face and remember that it is not the U.S., you will have a great time. I always meet people on scuba/snorkeling trips, and end up partying with these people later when I see them at Fido's/BC's/Coconuts/Palapa, etc. As long you use some common sense (you know, big girls out walking after dark stuff), you will be fine!
