This whole thread shows that whatever hotel management system this ship uses is totally out of whack. First, with respect to the cabin with known problems (the OP walked into the first room and a fan was there), the housekeeping manager should have taken this cabin off the "ready" list.
Upon embarkation, lots of things happen and it's possible that the staff was waiting until most of the checkin was completed to give the OP the best possible cabin. Then two occupied cabins were given out. I'm sure the only reason the prize was made available at Bingo was the hotel management system showed two unsold suites. Either those suites were really sold, or the ones actually empty did not show up as "ready".
RCL hotel management on this ship: Needs work
OP's sorrows: A bit too played out for me. I could never have made it through all 7 continents in this world with that 'tude.
