Hi!
We just got back from our trip in which we used Ticket Mania for our tickets. We elected for the hotel delivery because we waited too long to order the tickets and would have been cutting it close had we selected the free standard delivery. Tickets were there upon check-in, along with all the other maps/guides they give as part of the hotel delivery package. After checking in, I chose to go over to the Guest Services counter and asked to have the paper tickets Ticket Mania issued be transferred over to our plastic room key card. Just makes it easier to keep track of one thing. No problems what-so-ever in doing this and they worked just fine for the duration of our trip. Also, for this trip we only really needed a 3-day hopper, but they were offering the 5-day hopper for the 3-day price. This worked out great because we ended up using a fourth day to go over to Epcot on our last day to quickly check out the new Nemo ride during the DVC member preview weekend. We had planned to do this on our second day, but by the time we made it over to the ride on that day, it was broken! Anyways, by having the extra days on our hopper pass we were able to go over to Epcot early in the morning on our last day without having to pay for an extra day! It worked out great! I would definitely recommend Ticket Mania without any hesitation.
Have a great trip!
