It all depends on the trip. If I've got a car, we tend to do an offsite meal whenever we arrive. With ME, that would be different. I would tend to NOT have an ADR the first night, in case something happens, the flight is delayed, we're running late and don't have time to eat breakfast,or we eat lunch at an odd time. Our meal schedule tends to get 'off' on our arrival day.
If I was planning to arrive at 2pm though, assuming ME...I'd probably hit DTD or our resort food court. We sort of like to check out our resort food court on the day of our arrival. Even though the rest of our subsequent meals there are breakfast - it's nice to know what the home court options are. We also usually get suckered into buying refillable mugs then.
