Depends on size. Full size Luggage I can fit 3 with the seats up. 5 or more with seats down.
I would love to know how you fit 3 full sized luggage because I can't. I once picked up a party of 4 with 4 huge luggage and I can only fit 2. I have to call home and get the FIT over. The FIT took care of all 4 luggage and 4 carry ons. I can't even fit a set of 195/45R17 wheels in the CT with seats up, the FIT can. The CT can't fit a 12,000 BTU AC... the FIT can.
For a car which is categorized as a crossover... the CT fall short on trunk space as it is more of a crossover with a hatch styled back plus a really raised trunk floor. The hidden compartment is a nice touch but holds cons when calling for trunk space needs.
Like I said and stated to the OP... you really need to consider trunk space if the CT would be the only family car, more so if you have a family of 3 or more that frequents traveling/vacationing.
Don't get me wrong... I have taken in all considerations before signing the dotted lines. I love my CT for what it is and at the end of the day I know for a fact that I do not own a soccer-mom-car.
Interesting perspective. Why do I say such? Trying to get proper-sized luggage pieces to fit into the Accord sedan trunk is like playing Tetris! The Accord sedan's rear suspension/strut location impedes optimal luggage placement, despite adequate amount of overall capacity. This is perhaps one of only major gripes w/ my 8th gen' Accord sedan.
(I wonder if this is the case w/ the Accord CrossTour as well, namely the location/position of the rear suspension/struts)
it is worse on the CT as I explained above...
also note how those rear pillars are
here's another shot of the hatch closed just to give you an idea (my FIT in the background stored for winter)
