Is there somewhere on board that I can get $1 bills in exchange for $20's? I have a heck of a time gathering $1's since we do all our banking online and every bank nowadays requires an account in order to do even the simplest change making transactions.

I know we don't need too much cash on board, but I want to have plenty of $1's for room service tips as well as for bag handlers at the port.

Does DCL have a purser's office or equivalent on board?
