I copied and pasted from the email I received.
To better assist you in planning your cruise vacation, we want to make you aware that Carioca's will be unavailable during your sailing as the area is being refurbished. During this time, Cabanas, our casual dining restaurant located on Deck 9, aft, will come to life with enhanced entertainment nightly as one of your evening dining experiences. There will be two open seating periods in Cabanas that coincide with main and second dinner seating times for our guests to enjoy.
Guess we'll see how it is...I'm not going to let it get me down. We have 2nd seating, so no view, but we have requested for just 1 rotation there and not 2 since it's a 4 night cruise.
