Sorry, Harry, we were on Grand Princess for New Year's and they DO have MUTS!
"A truly happy person is one who can enjoy the scenery on a detour."
There are three Princess vessels with Movies Under the Stars, and Grand is one of them! Yippee! We loved it. Can't wait until all of Princess ships have it! If you want to know the name of the third ship go to www.princess.com and do a search for Movies Under the Stars. Sorry I can't remember which one it is just now.
