Yes, we are working on wich date we will eat at Ohana right now. It was at the top of our list for a while.
What else is on your list? Make sure you ask yourself, "Can I experience this anywhere else?" That's what we kept asking ourselves as we made our dining plans. If our answer was "yes" we kept looking for other places to eat.
Wow - first trip? Sounds wonderful. I have been over 100 times, and still haven't reached the age of 15. LOL - so... just have fun, and I don't have many suggestions, but having stayed at the value resorts, they're decent for the money, and DO have bus transport, so... HAVE FUN!!! Enjoy your stay - the castle is a beauty to behold, seriously.
