Be careful with this! On our last Navigator cruise, on the last night, we were told that the dinner was 'complimentary' for my wife and I. So we gave them a great tip. A few days after the cruise, not only did they charge us, but they got a very nice tip on top of that! We called, but Royal would not do anything, said they'll look at the records but that we should've disputed ON THE SHIP! We didn't know! Oh well, lesson learned! As Mama always said, nothing in life is for FREE!
