Travel expenses are up on everything from airfare to gasoline, so plan ahead to save money, even on souvenirs. Here are some ways to save: Book airfares on Mondays-Thursdays for generally lower rates. Pack light to avoid excess baggage fees (and make it easier to carry). Shop around for rental car rates and deals. Rent a car that’s easy on gas. Check out discount web sites for hotel deals. If you are traveling with kids, or going to be gone for more than a week, consider renting an apartment or home with a kitchen.
