Hertz - Cadillac SRX or Chevy Traverse

Have both SRX and Traverse rented for a 8 day stay in Maui at OGG. Will be 4 adults with 4 large 28" suitcases and carry on's. I would like to ride around Maui in the Caddy, but I am afraid we will have suitcases on our laps to/from airport. I have rented the Traverse before and know it will handle the suitcase situation. Can anyone provide experience with the SRX and luggage without folding a seat down?
Thanks!

I would think you would be able to put two suitcases flat then stack another set on top and be fine. Then just squeeze in the carry-ons. Obviously the less carry-on the better.

Here is another picture I found loaded up:

Go for the Traverse!! tried an equinox last year with four suitcases and four carry ons, plus our wives handbags and shopping - no way would it all fit in ..Avis kindly upgraded me free of charge to the Traverse when they saw the trouble we were in.

Thank you all for the feedback!!

Go for the Traverse; the SRX might be ok for 2 adults and luggage, but 4 adults and 4 pieces of luggage will be tight.
