I would think that you would have no problem with either of these scenarios. We have two 7:30 breakfasts scheduled on our next trip, with hopes to get to various parks by 9:00. Cape May is a buffet, so you can regulate the timing of your meal pretty easily. I've never had breakfast at 'ohana, so I'm not really sure that that works. You may want to let your server know that you are trying to leave the restaurant by a certain time, so that s/he knows about your time constraints. Have fun!
