Granted the top was up, but a trip to Costco, family of four and it all fit in. With the top's panels (in the trunk) in place (so the top can come down) you can't fit a small rectangle roll on piece of luggage in directly. You need to first move the panels up and away, put in the luggage, then put the panels back in place. Too much trouble for us, easier to use a small carry on bag and pack light.
