Originally I got a group code from beaches and was just going to help everyone book individually. We go out of the country on vacation all the time so I figured end it wouldn't be to hard. However, we are having a large group as well so we decided to go with a travel agent and block some rooms. I highly recommend it get a TA that way you don't have to worry about everyone booking rooms! We had a little trouble with sandals/beaches allowing us to switch from a group code to a group contract but the travel agent dealt with all of it she is great!
