DH wants to see the fireworks and thinks going to the early one and then seeing later ones (if we're awake lol) from the hotel is good. Nevermind the general difference has been about 500 bucks in my quick search right now between inc. NYE and going after.
A few of the hotels offer kid package things, so that might be a plus. Will keep looking. Thank you all for your help, keep it coming if you have more.
There are some great spots that you can get to by water taxi.... Fun with the kiddies!!! That are not to rowdy last year we were at birch grove point.... Great view! Or anywhere in balmain really... I have done the main fire works .... And yes it is busy but it's mostly alcohol free, and quite well patrolled by security and police. Sydney is a beautiful place and I'm sure you will have a great night what ever you decide to do
