Apres nap, freshen up with antiseptic wipes or watered-down paper towels. (If you've dished out the extra cash for an airport-lounge pass, you might have access to a shower where you can freshen up.) Airport hotels are now beginning to open their gyms at a nominal per-use cost as well. Aside from hot showers, towels, and toiletries, fitness centers offer access to workout equipment, saunas, pools, and even classes—not too shabby for about $15 a pop. Several North American airports have such facilities, including Chicago O'Hare, Detroit, Las Vegas, and Vancouver. Keep a change of clothing in your carry-on bag and slip into it to feel like new, too.
