We do this on every trip but we actually EAT at every meal. When I'm with my father we have ADRs for breakfast, lunch, and dinner and go to all 3. There's nothing wrong with that?
I will probably be making multiple reservations, due to the fact that my 90 days will come due, most likely before the calendar is out. We only do 1 park per day, and if the schedule is not what I expect, it will throw everything off.
