Can anyone explain to the uninitiated what all this means? I just booked my first DCL cruise yesterday... actually, my first cruise ever. When booking, I selected the room# for my class 5A, deck 10, room 10554. I presumed this was a room reservation... What is a GTY? What is VGT? Do upgrades happen? Do DOWNGRADES happen??? Another question I have is, I've chosen a location closer to stairs/elevator for convenience... Is there much of a noise issue in an area such as this? are there other drawbacks I haven't considered?
