Very interesting and informative travel guide for kids!
Format: Kindle
I do not have a kid myself but got a chance to travel with my niece to Washington DC recently. I was worried about how I could keep her interest and excitement during the trip, (as you know it is not always easy to travel with the kid when you are not experienced) and I am lucky enough to have found this book. This book is like a normal travel guide but it is specially designed for kids, with a lot of fun games, interesting information, and colorful layout. It asks you to fill in information such as when did you go, where did you do, etc, which I think it can serve as a memory book for my niece and remind her the trip when she grows up. I will definitely purchase more travel guide from the same series!
