Walt Disney World resorts using iPads for check-in
Apr 20, 2013

The Walt Disney World resorts can now use iPads to check guests in. The "Mobile Lobby Experience" is part of MyMagic+ and with this system, guests can be checked in from the lobby, or even curbside, if needed. In the past, cast members at some hotels have had rolling laptop carts as a way to take some basic information from guests before they approach the main check-in counter. But, MyMagic+ is all about guest convenience and the "Mobile Lobby Experience" seems to be the next step in this direction.
