To me, I think that it does not fit very well with the image that they are trying to change DCA into, with all of the new attractions, etc. coming to the park. While it may seem interesting and entertaining, and it appears that the event has been well received, I am not exactly sure that Walt would have liked having something like that in his park. Sure, it keeps people there and entertained, but I think that they could have came up with something a little better, IMO.
For us, we were not interested in the event at all. It was too loud, and to many people drinking. I mean, there are what 3 or 4 bars set up in that small area? It all just seemed a little over the top for my tastes. And FWIW, I have an occasional drink, enjoy dancing and clubs, but it just doesn't fit into the Disney image I guess. I would much rather fill my time riding rides, or watching entertaining shows while at DLR.
But..... that's just my opinion.
