Enter our Best Travel Tip Contest and you could win a $15,000 vacation for four to Condé Nast Traveler readers' favorite U.S. city: Charleston, South Carolina. 

For the next month I'll be sharing the cream of the crop of tips that readers are entering in our Best Travel Tip Contest. Today's tip comes from Pam Mandel, who writes the travel blog Nerd's Eye View, and they are words for a hardcore global nomad to live by:

"Spring for a shower. Nothing clears the cobwebs after a long-haul flight like a hot shower. Frequent fliers and business-class travelers know this and head straight for the lounges, but what about those of us on coach fares with no perks? 

Good news. Munich has showers, and Sydney, and Singapore....More and more international terminals offer showers for cattle-class travelers. Four times this year I've stumbled into the immaculate shower cabinets in Schiphol Airport, Amsterdam, and gladly paid my 15 euros. I emerge 20 minutes later feeling refreshed, clean, and perfectly content to use the rest of my layover time for window shopping, coffee, hitching on free wi-fi, and people watching. The relaxed folks with wet hair? They're the ones who know where the showers are. Check the airport directory or have a look at Sleeping in Airports. All of the airports on their "Best Airports" list have showers. Prices vary, of course, but I find the overall improvement in my well-being is worth every cent." 

Have you entered your tip in our contest yet?  You're just as likely as anyone else to win the $15,000 vacation, no matter how good or bad your tip, so it's well worth the 10 seconds to enter.  Those of you who submit a stellar tip, however, may well find it featured here, as well as on Condé Nast Traveler's new Web site launching next month. Good luck!
