We stayed at the Novatel Hotel in Mississauga Ontario over the weekend, and I was VERY worried when driving in their parking garage. But from the check-in desk, I spotted a black Armada on the roof, so I knew I'd make it.
The sign said clearance 6' 6", and man it was close! Take it SLOW over those speed bumps, I bet the roof rack might just hit if you bounced it too hard.
The thing that had me worried more than vertical clearance was whether we'd fit down their EXTREMELY narrow ramps. You have to make a 90 degree turn in about 15 feet to fit into the up / down ramps, and we cleared each side by a couple of inches.
Thank GOD the Armada can turn on a dime! Six ramps to get up, six more to come down. It was an interesting evening.
