Hi, I will be visiting Sydney in a couple of weeks with 2 kids of mine. I would like to rent a van - a 7 or 10 seater. Can someone tell me the following: 1. How much would it cost to rent a van (with and without insurance)? 2. Would it be cheaper to book for a more than a day? 3. Can I book it online in advance from Canada before I leave? Thanks for your time..
