11. Ye shall receive On a recent trip to Tucson, I asked the woman at the visitors information center if she had any two-for-one coupons for area attractions like our visitors center in Seattle does. She did even better than that, producing two free tickets to the next day's spring-training baseball game at Tucson Electric Park. Charlie Tiebout, Seattle, Wash.

12. Big-box bargains If you're on vacation in southern California, check out a local Costco for discount tickets to theme parks such as Universal Studios, Legoland, and the San Diego Zoo. Michele Sinclair, Playa del Rey, Calif.

13. The winning shot When our kids were younger, we gave them disposable cameras and held photo contests on family trips. We'd come up with different "best photo" categories—of a meal, a seashell, a sunset, etc.—and hand out awards at the end of the vacation. Wendy VanHatten, Sergeant Bluff, Iowa

14. Pass go If you fly to Singapore on Singapore Airlines, hold on to your boarding pass. It gets you a day pass on the airline's trolley, which goes through all of the city's major tourist zones, for only $2.20 (the regular price is $9). James C. Wernicke, Sandia Park, N.M.

15. Upon reflection A small table-top mirror would have been wonderful on my first cruise last year. I'm used to sitting down when I put on makeup and style my hair, but the mirror in our cabin was so far from the chair that I had to stand in order to see myself. I just bought the perfect mirror for my next cruise, in November, at a dollar store. Joanie Martin, Fox Island, Wash.

16. Big savings Southwest Airlines encourages large passengers to book two adjacent seats. If you do this and the flight isn't sold out, you can request a refund after the trip by calling Southwest Customer Relations (214/792-4223) or sending the airline your flight information. Dayle Cohoon, Tracy, Calif.

17. Watching time fly When our grandkids asked how long the drive from New Orleans to Dallas would take, we told them four movies (which was eight hours). They loved that they could fit in so many movies on the trip, and they didn't keep asking us how much longer we had to go. Now we always give them driving times in DVDs. Cyndy Nordyke, Hurst, Tex.

18. It's in the tag Magellan's Retriever Luggage Tags have a message in eight languages telling baggage agents to check the itinerary in the tag so they can forward a lost bag to you while you're still traveling (magellans.com). Nona Tyler, Winter Park, Colo.

19. Take a compliment I pack a box of thank-you cards when I travel. If I get great service from the hotel or cruise staff, I leave a card. Most people in the service industry receive feedback only when it's negative, so compliments are refreshing. Jen Keivel, Beavercreek, Ohio

20. A sap story While I was at a restaurant in Pompeii, some sap dripped in my hair. I tried soap and water, but it didn't come out. Then I remembered I had Purell in my purse. I rubbed it on my hair, and it removed the sap! Mary Peters, Del Mar, Calif.
