I am cruising with my girlfriend and we have received $900 OBC to use on the cruise. We typically pay our own items since we are not married yet, and don't have shared finances. We'd like to spend the $900 solely on drinks, food, and the such.
How can I avoid my gambling (typically spend $700-800) from digging into her half of the OBC? Obviously the first $450 I spend will be "my half" of the OBC, but what about after? Can I take cash to the cashier and have them put it into my casino wallet and bypass the OBC completely?
Sorry if this is an amateur question, we've never cruised (3 times before) with OBC.
