I see others have replied, but here's my experience.
I ordered a Disney e-gift card from Target. I had it exactly four hours later and loaded it into disneygiftcard.com right after, combined it with an existing physical card, and boom. Done.
It says on the
Disney Store site and the Target site that the e-gift cards can be used for the parks, tickets, resort stays, etc.
I'm definitely going e-gift card from now on. The last time Fed Ex "delivered" gift cards to me, they left them hanging on my neighbors' front door. This was after spending an hour with them and Walmart on the phone (gift cards were from Walmart) explaining in detail how to get to my house. Their first attempt said I had given them the wrong address and/or was no longer living at the address, the second attempt said I wasn't home, and the third attempt they left them at my neighbors'. Granted, it's a rural area with a long gravel driveway involved, but they'd promised to call me if they didn't personally hand the cards to me (I stayed home all day waiting). They never called, just left the package at the wrong address and left. That was $250 worth of gift cards hanging on a front door handle.
I hate Fed Ex.
Sorry for the rant.
