I have 2 rooms booked for a group of 7 of us. However, I did not make it clear to my TA who to put in each room, and everyone ended up booked in the wrong room. I need our group of 3 and group of 4 to have their rooms swapped. My TA said she is unable to reassign the rooms because FCC was used? Should I ask her to just cancel and rebook the rooms with the correct assignments or try to sort it out when we board? I just don't want to start our trip with having to deal with a hassle of switching room assignments.
