Hi there do you do a package for toll roads and bridges ie the golden gate bridge and how much does it cost?

I don't think they have such an option

In my car there was a plate with a bar code with could be opened/closed. So if you decide to go over golden gate or paid road with fasttrack you can open that bar code and Avis will charge you for using it afterwards. But make sure to ask about details on the counter

They have the toll pass come with license plate and they will charge when you return.

No

It's automatically added to you bill from each time you go over and back etc...so no to package, as they don't know how many times you will hit the tolls! But it's all easy
