I know what not to do at spas. Don't talk on your cell phone in the relaxation area. Don't expect one massage a year to get rid of all your muscle tightness. And don't drink alcohol before your treatment.
By all means, enjoy a Rum Swizzle at Swizzle Inn while you're visiting Bermuda -- just don't do it right before your spa treatment.
But when I'm looking to avoid common travel mistakes and pitfalls myself, I turn to other About.com Travel Guides. Our collective wisdom on what not to do all over the world is now gathered in one place, thanks to Susan Breslow Sardone, our Guide to Honeymoons and Romantic Travel.
"I now know it's fine to belch after a meal in China, to avoid wearing camouflage clothing in the Caribbean, never to leave a big tip in Norway, and not to honk my horn in Hawaii," says Susan. Even if you're not going to Sweden or Paris anytime soon, it's fun to check out what not to do there.
