I'm going to be blunt, Dancin' with Disney is WACK. It's cheap entertainment and it definitely needs to go. I'm not up for a meet and greet, either. Like disneytwins said, this isn't WDW where there are a whole bunch of meet and greets everywhere. They're not needed as much at the DLR. That building should be used for something else. What, I don't know but not Dancin' with Disney or a meet and greet.
Do you have kids by any chance?
Or do you like a nice place to take a long break from the heat during the summer and relax with a drink and enjoy watching kids have a blast and do some dancing yourself with rarer characters?
Not every part of the park needs to be a big huge spectacle and not every part needs to be exactly your cup of tea.
