Kind of, if we had prepaid the gratuities and the shore excursions our obc would have more than covered us. That being said on our last B2B, we bought one drink each and one shirt for DD in the gift shop. Being frequent cruisers at the time, we already have all the DCL gear we need lol. Not sure if the placeholder counts too, we bought that on the second leg. Moral of the story though, is that we for sure use the OBC to try and pay for as much as possible.
