Last cruise we rolled on our luggage, just 21 inch suitcases, but the ramps to get on Wonder almost did me in. Very difficult to get that suitcase up all those ramps.
Disembarking, we let RCCL take them off and one of our suitcases was missing.
We had to file a report and wait to see if someone else brought it back.
Next cruise in March, I will do the reverse.......let RCCL bring it on and I will carry if off (all downhill).
