We cruised in 3 staterooms on the Fantasy last February and stayed at the Hyatt the night before. I did the online checkin for all 3 rooms at the same time on the first available day. We booked transfers with the reservation so did not pick a port arrival time. We were on the second bus leaving MCO and got thru security quickly. There was no line for checkin and my friend went to an agent next to me for her room, booked by myself with my rooms and again I did all of the online check ins. Both agents were done at the same time and my sister and I had boarding group 15 and my friend 5. I politely asked why and her agent said she probably did online check in before me. I politely said that no , I had done all of the check ins at the same time and our agent then gave us all boarding group 5. My friend would have just waited to board with us and as my children are teens we would have been fine waiting, especially as once boarding starts it moves pretty quick. I was just curious what the reasoning was but did not get an answer and was clearly not related to any differences in online check in or which bus we arrived on from MCO.
