Toyota Sienna luggage space
 

We have an 8 seater booked with Alamo.
4 adults and 4 children (9-12 years old).
How much luggage will we squeeze in?
Staying at a villa so can travel light if needs be

I also have a Toyota Sienna booked for my trip on 20th May, 7 adults and 1 child. After extensive research I have come to the conclusion that we'll be lucky to get 2 suitcases in the back, not even close to what we require.
Easiest solution is for some of your party to use a taxi/Uber from/to the airport so you can utilise more space for cases with the rear row folded down.
Yes it's a bit of a 'faff on' but only realistic alternative is to hire a 12 seater minibus and if you are anything like me, I don't relish being a bus driver for 2 weeks so taxi solution for us.

We have travelled with 5 adults and 2 children and had room for 4 full size suitcases plus all hand luggage in a Toyota Sienna. Yes we had the hand luggage in the main foot wells but all cases fitted in boot. It’s only a squash to and from airport so didn’t find it an issue.

We had a Sienna for 2 trips, 4 adults 2 kids, 5 cases and 6 hand luggage and a buggy. It was tight when moving between hotels but certainly doable. You'll certainly get 4 cases in the boot. The foot wells are surprisingly big too.

We had a Kia Sedona (8 seater same class as the Sienna) for 5 adults and 3 children. All had a case/large holdall and all adults had hand luggage. All fitted in! As others have said a bit squashed to an from airport and had hand luggage in foot wells but very doable!
