I absolutely think that you will. We've done this in the past and it worked out great - even got a few rides in prior. I would recommend getting to your ADR a little early, they will take your picture, it's a buffet so you can pace your eating and be able to meet the characters as well. It's a lot of fun!! When you are finished, it's a short monorail ride to the MK from the GF! Piece of cake!
