Zoo!
You might find you are paying a thousand dollars a night for a 3 star hotel and during this time many have a minimum night stay so you cannot just stay on NYE. They sucker you in for as much money as they can.
The crowds are horrific if you cannot view the fireworks from your hotel or room. If you want to view the fireworks from a good public vantage point you need to stake your area of grass very early on in the day.
If you have the bucks to spend it would be fabulous.
