Under the explore ship section for the Venezia, it still says this when you click on each stateroom type.
So one place says daytime, the ship stateroom description says exclusive. If other Vista ships are exclusive, I would hope these are as well.
A Terrazza Cabana stateroom gets you real estate on one of the most desirable addresses on the ship: your very own lounging patio, complete with deck chairs and a hammock. Plus, you'll have easy access to the exclusive Terrazza Carnevale area. (All Terrazza stateroom guests must be 12 or older.)
Amenities exclusive to Terrazza staterooms:
Access to the Terrazza Carnevale area for that seaside-lounging lifestyle
Morning access to the Carnevale Lounge for a daily continental breakfast
Specially-curated brunch on select sea days, with a complimentary Spritz or Mimosa
Sailaway event at Terrazza Carnevale, featuring live music
Comfy Terrazza-branded robes and towels for your use
