Does anyone know if there are any issues arriving after midnight? I have a reservation today, April 29th, but might not be able to make it in till 1 am April 30th... is there any risk of them cancelling my reservation?
Call the hotel and let them know your arrival time. It should be fine. I've arrived at WDW hotels around 1am before and it's okay. I think as long as you check in before the system does its daily turn over (somewhere around 3am), it won't drop your reservation.
