This made me think of something. Maybe I should book a dummy 7 day cruise just so I'm locked in on that greater OBC. That way if they ever change it and make it lower or even change the requirements for an OBC maybe I'd already be grandfathered in??? Seems like I remember someone being mad at something they lost when rules were changed and they weren't informed or grandfathered in. I'll have to think about that and crunch some numbers.
