NOPE. Don't do it unless you're talking little kids with little suitcases for 3 of those people, but I don't think you would be... I had a group of 4 with checked bags (close to airline max size), 4 carry on's (backpack size) and 4 personal items (purse/laptop bag). The dinky "SUV" we got could only technically be called an suv and while it could fit up to 5 passengers it couldn't fit us and our luggage safely. We had stuff in our laps for the trip and then some luggage slid and would have hit the head of a passenger in the back if not for the fast reaction of the person sitting next to her, after which we dangerously held that luggage in place for the duration of the trip because better our arms get broken if anything happened than her head. There is no way in heck I would try to fit 5 people and luggage in 1 XL- I won't even do 4 anymore. Split that group up into 2 rideshares, private transport it, or Mears it.
