Look at the top of the forum (sticky post) and you will see roll calls for each month with dates listed. Copy clip it into word and you can print out a list with pics of who will be there the same time as you. Takes a little work but I do it every trip so I know who is who. As for meeting them - the bar is the best place and look for the orange wrist bands.
Leave your inhibitions at home. Take a good attitude and minuscule clothes and you will have a great time. Book a Boobs Cruise. Be prepared to see no other part of the world as you'll keep coming back!
