Hi there Rossana,
Sounds like you have planned the ultimate coast to coast Disney adventure for 2013! Hitting both U.S. Disney Resorts back to back will be an experience you won't soon forget!
Unfortunately, the PhotoPass+ Package will only allow for photos taken within 14 days from first use to be added to the account. If you were visiting Disneyland within that 14 day window, you could use the same package at both resorts, but since your Disneyland trip is months later, you would have to purchase a new package for that visit.
The good news is that the Disneyland PhotoPass+ Package can currently be purchased at a discount using the
Pre-Arrival Offer link. The Disneyland package costs much less than the Walt Disney World package and I think the price will surprise you! It's a great deal!
As someone who frequents both Disneyland and Disney World, I am happy to answer all of your coast to coast Disney Parks questions, so please keep those questions coming!
