couple weeks ago we went to our local
Disney store to buy tickets- and they told us that you were NOT able to link them
just called our local Disney Store today & did online chat with cast member on Disney World website today-
both said you currently CAN NOT link tickets bought at your local Disney Store to My Magic+ (My Disney Experience )
ie not able to book fast pass+ reservations before your trip
Buying tickets from Disneyworld.com
only ONE disney gift card & other form of payment (credit card) and be used online.
HOWEVER....
you can call disney world ticketing and use MULTIPLE Disney Gift Cards to buy park tickets (we did this last week using over 20 GC)
The cast member will give you a conf # (and they will also email you conf info)
Our phone agent stayed on the line with us...asked us to log into our My Disney Experience account (from WDW website)
and then walked us through linking the tickets we just bought to our account.
it's very easy (we did not need their help) but was great to see that the cast member wanted to make sure that we were able to link our tickets successfully
