I won't miss it.
My daughter will.
She never knew it any different.
But, that's what Disney does. I remember her complaining that they replaced Kim Possible with Phineus and Ferb (even though she LOVES both IPs)...
It's lost Disney...and now it's time for the Hat to say goodbye.
And, I've said this before (and this thread is proof), when you have a part of the park that is there for more than a decade, it becomes part of the "park" for a vast many people who "grew up" with the parks.
So, yes, while I'm glad to see it go, as I grew up going to MGM (not HS) and was there opening summer, etc...I know my daughter will ask us on our next trip, "Where is the hat?"
That being said, it was nothing more than a photo op and a pin trading station, at best.
So, while I'm among the group who wants to see it leave Hollywood Blvd, I'm not among the group who wants to see it disappear. I think it would work really well elsewhere, but just not where it sat.
