This is We believe , first an upgrade has to be done at the
port. that is not on the actual ship once u step foot on the ship it is to late must be done at the ticket counter in the port building ....
Second .... W did this We had booked a Cat 10 on deck 5 Yes it was a secret porthole room , witch is like an upgrade u can give yourself....... if u boook it... to cat 4 on deck 8
there was no Cat 3 avaliable ....... so off to stateroom 8502
we went there where several rooms in this cat aval.
ok so for the cat 10 s/r we paid 1700.00 and the upgrade was $1000.00 so for the whole cruise $2700.00 for 2 people
and we also recieved a $100.00 ship board credit
for what i dont know upgrading u guess ???
and the other shipboard credit we already had of $100.00
so i think it was worth it loved the room location
next time back to cat 10 , but we liked it so much we did upgrade to cat 7 already going to try nav verandah
