I've only ever bought direct through Disney. Are there any drawbacks from buying through something like Undercover Tourist? I've always been curious, but have never looked into it for some reason.
I buy through Disney using discounted Disney GCs. I buy them when I can get 4x fuel points and 3-5% cashback on my Chase Freedom or Bank of America card, thus saving me 16-19%. Much better than even UT.
Another Undercover Tourist fan here. I also signed up for the free email newsletter from Mousesavers.com which gets you an extra little discount from UT.
I've used UT for several trips, but this was the first time I went with the E-Ticket option. I got my ticket code almost immediately, linked to MDE easily, good to go!
