This is a mite unrelated, but I do want to give a shout-out to Undercover Tourist...they are super...
I've had two problems (over many years and many purchases) w/UT...and both times they were beyond wonderful.
The first time was 100% my fault...I just ordered the wrong thing (somehow clicked on "child" ticket when what I needed was a ticket for my 25-year-old DS!)...they fixed MY error next to immediately...and while I did (of course) pay the "extra" for the adult ticket, they didn't charge me a penny for the change...
The second time something went wrong somewhere--no one knows how or where--but the PH we got from UT was "empty"--i.e., despite having bought a 7-day PH, we got a ticket w/no days of any kind on it at all...we discovered this when we tried to link the ticket to a magic band...
Ultimately, Disney & UT worked out between the two of them...but once we got onsite (to the new VGF--LOVE that resort!), the work-out was smooth and they were very, very nice to us...(trying to deal w/Disney IT ahead of time, not so much...I do not have the same high praise for Disney IT!)...
Anyway, the high likelihood is that your tix will arrive soon and you'll have no issues or problems...but if something does go wrong you can rely on UT to sort it out and make it right, in an almost painless way!
