We've sailed on RCCL, NCL, Carnival and have an upcoming cruise with MSC. On all the lines we've sailed with we can make reservations for 5 in a cabin, except with RCCL. The travel agent had to book 4 under one reservation, then a single person under another, then link the two reservations. Makes no sense and I'm wondering if anyone knows why RCCL does it this way.
On a related note, is it possible to determine total pricing for 5 in a cabin before booking?
