We got "stuck" into doing self disembarkation on the Conquest. We were so busy having fun the last night we forgot to get our luggage out before the cut-off time. Luckily we were able to handle all of our luggage and do it. If you chose to do the normal disembark proceedure you will probably still be off the ship by 10:30 even if your "color" is called last. The problem with trying to do a beach in San Jaun before flying out is what to do with your luggage. Maybe check in at the airport and give them your luggage and have one carry on? Then you could taxi back to a beach? But then you are sweaty and sand covered for your flight home. Not sure I would want that.
