We've been three times and really enjoy it.
First time we went we weren't too sure what to expect - it was superb. Lots of character interaction (dressed differently in their Halloween gear), the Headless Horseman parade is good to see (two different times each night). And all the candy you can stuff!! We always seem to come home with loads.
My DD and DH always dress up (I'm obviously a stiff cos I only get a wacky Halloween t'shirt, jewellery etc

). Last October there didn't seem to be quite so many people dressing up, but still hazard a guess around 50% do. Have to say, I've never seen so many pirates in my life, last October - it was hilarious. Every shape, colour and sex
We also visited SeaWorld who had their own halloween stuff on (during normal park hours). Obviously no different to a normal day there, unlike
MNSSHP, but it was fun nonetheless. To be honest, it was more geared towards the children, but it doesn't stop me

There were lots of different little stops to get candy in your bag, characters and people dressed as flora and fauna. There were some very funny little sideshows going on, too.
Halloween is our favourite time of the year to visit the States. We love it
