Does RCL have a program like Disney for express walk off if you bring your luggage? If so, what time are you off, and do you HAVE to leave first or can you just leave when you are ready? We are going on a cruise where we dock on a weekday and I'd like my son to go to school that day (his school is 10 mins from port). I think we need to be off ship around 7:30 to get him to school on time and trying to figure out best plan. I'm assuming if we don't have express we may not be off until later, but I don't want to be forced to leave earlier than necessary if I do express. Thanks!
