Located inside...yes INSIDE...the McNamara Terminal at the Metropolitan airport. Guests need not even leave the terminal and the hotel has its own security gate for check-in (nice touch). Even better, those not staying overnight at the Westin but who have an hour or two to kill while awaiting your flight can sweat inside the hotel gym for $15 (hotel guests for free).
The 24-hour gym stocks a decent collection of Life Fitness cardio and strength equipment as you can see from the chart on the right. While Westin Detroit claims you can swim laps in its pool, you can't really...unless you don't mind turning around after every 15 or so yards.
Shower facilities, towels and lockers are provided for your post-workout clean up. Starbucks Coffee is served in the lobby shop, which also stocks Powerbars and Gatorade. And, the Asian flare restaurant, Dema, receives high marks from our athletic-minded travelers too. What a great way to prepare for your next flight!
