As Rudi pointed out, with MSC all things are fluid. I remember having to run back to the YC to refill a drink if I wanted to walk around or spend some time in the rest of the ship. I don't know of any upcoming changes, but would not be surprised. Actually, to clarify Rudi's comment, a few years ago, even YC passengers had to pay a bit extra to get the super premium liquors (JW Blue, for example).
