Found a Canadian Residents rate for the OS.
However, it's not worth it for the extra $.
The whirlpool bath is very narrow & only for 1 person.
The tub enclosure is too high & almost fell getting out of the shower.
There is no hand rail to hold getting im or out of shower.
The Encore theater is also flawed. There is a huge space above the bench seats. People walking behind could easily trip & fall into that space. There are some raised lips & narrow spaces for people to squeeze through to the seats.
The Gathering on deck 10. Tables are much too high. I'm 5'7" & was uncomfortable.
Crew ( Team ) members talk amongst themselves in their own language. Some barely utter a greeting. Food was ok. There are a lot of trivia games, one after another.
Entertainment: 4 comedians, 1 juggler, 1 magician, 3 production shows.
Our stateroom steward never introduced himself to us, so I never knew who he was.
Walls are paper thin. Kids running in hallway. People being inconsiderate late at night, not whispering when returning to staterooms.
This was our 2nd Carnival cruise but even DH doesn't want to cruise with them again unless it's an interesting destination.
