Many of the resources on the More Great Info page also have travel tips, but here are my favorites:
Gluten Free Globetrotter — travel tips, links to travel websites, information about GF tours and getaways, and much more! “Your ultimate gluten-free travel resource.”
CeliacTravel.com — gluten free travel tips, articles, stories, and more
Triumph Dining Cards — ten languages, laminated, specific for each cuisine
CeliacTravel.com gluten free restaurant cards (free) — 54 languages, print-your-own, general information
