Because we're full-time nomads, our collection of worldly goods is pretty small. However, there are still a few things we find useful and enjoyable for travelers that would make great gifts.

Maps: Travelers love maps of all kinds. Forget GPS - that's great for driving directions, but not for dreaming of destinations. A fancy globe makes a lovely high-end gift, but even an inexpensive paper map of the United States or the world (free with a AAA membership) is fun for travelers. Add some colored pins or stickers so your would-be wanderers can mark where they've been - and where they want to go.

Gadgets: We like gizmos that enhance our trip but that don't weigh us down. Noise-canceling earbud headphones tune out surrounding chatter and engine hum on long flights. Anyone using a mobile phone as a camera will appreciate a power bank, which provides extra juice when all those selfies nibble away at battery life. Prices/quality of electronics vary, so we suggest checking online reviews for models that suit your criteria and budget.

Books: Titles that inspire wanderlust are always a popular choice. We used National Geographic Traveler's 100 Countries, 5000 Ideas to plan our round-the-world journey. The Travel Book by Lonely Planet, written for ages 8 and up, is a great way to introduce kids to the world. These publishers, along with Dorling Kindersley (DK), also offer several beautifully illustrated titles of the world's-best-destinations variety.

Plan a trip: The ultimate gift for a traveler is a journey. It doesn't have to be a luxury week in London or an African safari. A weekend at a B&B, a night camping, or even a day trip to a museum or other nearby attraction will fill the bill. You'll be creating memories that will last long after the snow melts and the carols fade.

As we say on our travel blog, "Just go, already!"
