I just took a look at Underground Tourist and it seems like their tickets are more expensive than Disney direct passes for the same # of days and features, without any
DVC discount -- just the standard anyone can buy direct from Disney. For example, Disney sells 4 day Park Hoppers for $425/adult.
UT sells the same 4 day park hopper for $431.95 (and claims you are getting a $41 discount even though it's $6.95 more).
Disney direct sells 5 day passes for $445 and UT sells them for $449.95. So presumably if you had the DVC deal right now you could get the 7-for-5 deal for $445/adult while getting 7 days from UT would cost $469.95 (for a 6 day + "one extra day" pass) or $485 for the 7 day park hopper).
What am I missing? Is the current Disney pricing a short term special? If so they aren't promoting it that way.
