So I have seen some people mention here and there about how they have been upgraded by the cruiseline. That has never happened to me, so I'm curious how often it happens (granted I know it depends on how much the cruise is sold).
Have the upgrades been on a big ship, small ship? How many levels have you been upgraded to? Does level of loyalty come into play?
I booked a guarantee inside, and understand that RCCL can wait until the day of sailing to assign my room, but is it worth waiting to see if an upgrade can happen, or should I try and spend what loyalty points on my CC (Which I've never used) for an upgrade?
