In all fairness to the people who visited in the first few months of this year... it wasn't very well publicized WHEN the parties were. ; All the propaganda we saw said "selected dates". ; Now, I'll admit, there may have been more specific stuff given to the people travelling with children... but somehow I doubt it. ; So really, in order to find out when (or even how much, or where/what exactly this thing is), you had to call someone.
Well... I can only speak for DH and I... we don't make those kinds of calls when we're ON vacation... and we didn't really hear much about it before we went (and it's not like we live under a rock).... so I think this one falls under the heading of "their own darn fault" if Disney don't think they got a good response.
But maybe that's just me.
