4. Pack a Laptop or Tablet for Hotel Room FastPass Swapping.
Even guests that reserved fast passes well in advance of their trip should bring along an easy to navigate tablet or a small laptop for any last minute dining reservations or fast pass swaps. Skip the fast pass kiosk lines in the park by making this switch yourself before you enter the park. Sure, you can use the Disney app to make these changes; I just find switching reservations and fast passes for entire families much easier on a screen larger than a mobile phone.
