Yeah, you're definitely not missing much.
As someone who frequents the parks more than the average guest, but not necessarily more than a local (I have been five times so far this year), I have to say that this LTM "promotion" has been especially awful. It seems like most of the "events" scheduled have been releases of limited time (extra-expensive) merchandise, with a few random shows or character greetings mixed in. The only Limited Time Magic I have experienced was the opportunity to buy a $30.00 t-shirt when I was there in April. I passed, of course, and just found the same shirt at the Character Warehouse at the Florida Premium Outlets in Little Lake Bryan last week for $6.99.
Honestly, if I were just an average guest (heck, if I were the same Disney nut I am now, but never went on the boards here) I probably would have no idea that they were even doing this promotion.
My problem with this "promotion" is not in some performances or greetings or the characters dressed up in different costumes that only a handful of visitors will ever experience (for 99% of them, I'm sure it's just dumb luck that they run into these things, rather than strategic planning). My problem with this "promotion" is that most of the Limited Time Magic is just some overpriced souvenir that Disney is trying to get us to buy.
Now, I'm not saying that Disney 'owes' us anything like the Year of a Million Dreams promotion every single year; however, if they're going to do something as stupid as Limited Time Magic, maybe just not do anything at all and put their resources into something that people might actually enjoy a year or two down the road...
