Got off the Reflection last week and we had a similar situation. We ended up using the OBC in the casino playing video poker. You can download any dollar amount following the instructions on a card the cashier gives you and then it's just keeping track of how much you've bet. We did it in $50.00 increments and played $1.25 a game (.25 game). We had to run $25.00 through which was 20 hands after which it then allowed us to cash out whatever we won plus the remaining $25.00. Then we were able to put another $50.00 in and repeat the process until we used up all the OBC. As long as you play 50% of whatever you put in, you can cash out and put in more OBC.
You also have the option of using the OBC in any of the restaurants (Tuscan Grill is really good and you get a discount if you book before you board), any of the shops, drinks, excursions or they sell IPads for $479.00 as well as Air Tags, IPad mini, and Go Pros.
