We are family of 6 - 4 adults and 2 children below 10 years. We are going to Venice Easter time for 4 days. Hotels in Venice are quite expensive at 150-200 per night for our family but airbnb in mestre is around 90 per night. We will arrive at midnight so we're thinking whether we hire a car and stay in mestre, saving on hotel costs but paying car hire costs or we stay in Venice town but save on car hire. But we will still pay for taxis and buses for 5-6 people each time we travel to Venice and also from airport and back. I have two questions:
1. If we stay in mestre can we drive and park near Venice town and then walk to all common sight seeing places?
2. Given we are 6 people including children does it make sense to hire car ( costs is 150 EUR for 7 seater for 4 days).
3. Any other suggestion for cheaper accommodation in or near venice
