We spent around 4 days in DHS last week to say goodbye to the park as it is. Saw Indy, rode TSMM, saw Fantasmic, saw the holiday comedy players, rode Star Tours, saw the Star Wars stuff including fireworks, had one last drink at the Studio Catering Co bar, said very long emotional goodbyes to Osborne Lights. It has been our tradition (for the last decade) to spend NYE in this park. Now we will stay home instead.
DHS just isn't going to be fun for the next couple years. We're due to return to Florida in Sep/Oct. We'll even stay at the Boardwalk for a weekend, but I think we will stick to mainly EPCOT. I might return to DHS for a character greet with Vader if he's still around but setting foot in that park will probably be like visiting a tomb for me. As soon as they put up the construction walls at Animal Kingdom I stopped going there.
I guess if you're a ToT or RnR fan, the park still holds interest. I can't see it being more than a 4-5 hour park though. And New Year's will be beyond sad. (Just not having Mulch, Sweat & Shears or any live band for the NYE party took much away from the night.)
If you're visiting over the next couple days, by all means go see all the chopping block attractions while you can. But after the next couple weeks, I'd avoid the park.
