We've been discussing this too. I'm not a huge fan of big crowds so the city doesn't appeal to me. Dh and dd1 would love it though.

We would love to go to or have a BBQ but dd2 is not sleeping so well at the moment so sleep is precious. But I have find memories of nye bbqs and parties growing up and loved them.

Last year we stayed home because dd2 was only a few weeks old. We discovered the locals here (only been here 18 months) set off a LOT of fireworks.
There are a couple of parks in our area with brilliant views of the city so we might have a picnic at one of those and watch the fireworks. Or might walk dd1 up to the park at midnight and let her watch them. Not sure yet.
