When we fly early in the morning and arrive at the resorts by 11, we book a lunch, since we hadnt really eaten all day at that point, other than snacks. We check in, but usually room is not ready, but we drop our luggage, go to lunch and usually by the time that is done, our room is ready. We unpack, take a swim, then spend a few hours in the parks while everyone is having supper! Early bedtime, as we wake up around 4am on those days with the early flights.
When we have later flights, we dont even stay at Disney the first night. I dont like spending the $$$$$ for 1/2 day or less stay, so we book a hotel for about $100 on Hotel Plaza Blvd and walk over to Disney Springs for supper/little shopping/watch entertainment. This trip we booked Raglan Rd for our first night (5pm). Its very reasonably priced (we're paying OOP too) and there is entertainment.
