I'll be renting with Avis for three weeks in California for myself and two other people. I was considering the Minivan class.

I'm new to this rental business and was wondering what are the chances that this turns out to be the Grand Caravan, preferably with a table in the back (I believe it is called Swivel 'n Go)? I've seen that the Sedona and Sienna alternatives exist from the fleet list.

I'll be using a US Airways discount code.

Any other tips?

Many thanks from Europe!
