I do multiple ADRs (2-3 per day) nearly every day of my trip. It's not for everybody, but I always enjoy my breaks in the restaurants.
Are both of your meals at H&V? If so, you may want to try and switch your Fantasmic dinner to another restaurant (just to add some variety). Although I eat multiple restaurant meals per day, I've never eaten at the same restaurant twice in the same day.
As others stated, it may not be a bad idea to see if you can get a better/earlier time for your breakfast. Other than that, have fun!
