We are going to 'Ohana's tonight, and our reservation is much later than we usually eat (the earliest time we were able to get when I booked 5 months ago). The kids (12 & 14) are probably going to be hungry and looking for their dinner a couple of hours before our reservation time. I have heard of some of the character meals charging an "entertainment fee" for non-diners. Is there something like that at 'Ohanas in case I end up letting them eat earlier?
