This decision by Carnival is a shame.you should pay the same as an obstructed ocean view room now that the doors don’t open!
The doors opening will not effect the a/c as the unit shuts down as soon as the door is opened. Think about it! Retrofitting the doors with fixed windows is a lot cheaper than putting in new expensive doors! And virtually no maintenance! Take it from one who has been in the window business for 30 years.
I will be rethinking my decision to book a 4K room on the Legend this January. I’m going back onto their website to find out if or how much more this room is than an ocean view.
