Just following up now that I'm back home on a computer. We did DHS for NYE and actually had a pleasant time despite the craziness apparent at the other parks. Yes lines were long and yes it was a crowded day, but it never felt overwhelming. We were able to get a spot on Hollywood Blvd at 10:30 next to the information board with ride and show times. The area eventually filled in but most people were respectful regarding space.
My only complaint was the countdown to midnight. The Mulch Sweat and Shears band was fairly entertaining but completely dropped the ball at midnight. They were still wrapping up their last song as everyone watched their cell phones go from 11:59 to 12:00. People started blowing their horns and you could hear EPCOT's fireworks going crazy. Eventually at ~12:02 the 'official' countdown took place. Sort of disappointing but the fantastic fireworks that followed immediately made up for it.
All in all we had a great time. If you plan on being in WDW for NYE I highly recommend DHS if you want to avoid a bit of the chaos but still take in some excellent Disney fireworks.
