Meet & Mingle is a small get together arranged by RCCL and another web site so folks who have been corresponding via the web can "Meet & Mingle" Once 25 people have registered for your sailing they will confirm a party for you. If you go to Royal Caribbeans web site under Customer support go to Frequently Asked Questions and follow the link to the Meet & Mingle. You will need your booking # to register. This is only good for sailings over 7 days. When are you sailing and on what ship? We are already confirmed for our 5/21 Voyager sailing.
