^^^ It can be done. We had 7:55AM Ohana's ressie on our AK day. True, you will be arriving much later to AK because your ressie is for 9:10AM. However, we were working against three variables: 1. we had light rain that morning (thank goodness we had the ADR at Ohana's until the rain died out), 2. hot weather in late June, and 3. large park crowds at AK. In spite of all that, we did AK after our Ohana breakfast, which was a blast! If I were you I wouldn't give up that Ohana reservation as they are difficult to get. The other option would be for you to keep checking for an earlier ADR at Ohana's the same morning, OR switch things around a bit so you can go to Tusker House on your AK morning. Some of our better ADRs came up last minute. Remember people have to cancel reservations all the time. If you can do both, I would recommend trying both Tusker House and Ohana's . We did both restaurants on our AK days. We had park hoppers so we were able to do AK two separate mornings during our trip. Hope it all works out for you!
