We had the same room so we were able to leave our luggage in our room. We were one of the last people to get off the boat had to go through customs and then go right back upstairs to check in. We checked in at the concierge desk and were allowed to wait in the concierge waiting area. We were given group number one boarding which allowed us to get back on the boat at around 11:30. We were off the boat for probably 1:15. Being back on you felt like you had total run of the ship while everyone else was getting there bearing down. It was great! I will say that the three day cruise felt way more crowded than the four day even though were both fully booked.
