Hi and thanks to all of you who helped me with an earlier request for places to go in Sydney with kids.
I'm now looking for areas north of Sydney where we can find some accommodation. There's lots of places on the map but to me they are just unfamiliar names and I'm after somewhere safe and nice. I thought we could find somewhere about 30 minuîtes drive from the city which would not cost too much i.e a travel lodge.
Thanks for any help
