Here is what Disney sent me in regard to the 10 day world ticket:
We appreciate your recent ticket inquiry.
Regarding the 10-Day World Hopper passes, the park hopper days do allow you to hop between the four main Theme Parks on each day of use. Hopping from one park to another on the same day counts as only one day of use.
For further information regarding the 10-Day World Hopper Pass, please see the pass literature, which should have been included with the pass. If you did not receive any pass literature, your overseas relative may wish to return to the location from which your passes were purchased to inquire about any further information.
Does anyone know what pass info. comes with the tickets from theflightshop?
I am still unsure about any restrictions, has anyone bought tickets from them?
