I support whatever it takes to make the rave last longer. A rave that ends at 1:30 is too short when the standard at most cons is around 2:30 to 3:00 am while others lasting waywards past that.
That was my only gripe with Otakon last year, the rave ended before it even felt like it started. I would suggest possibly talking to the Hyatt in regards to their space of ballrooms, as they're connected to the convention center through a walkway as well and seem to have a great large ballroom right by the doors that lead to the convention center.
