Loved by an 8 year old
I bought this for my friend’s son when they were taking an 8 hour train ride to Washington DC. He loved the activities and reading about all of the DC sites! It kept him occupied for the majority of the train ride and he carried it with him when they went site seeing! It was age appropriate and developmentally appropriate as well. Just make sure to pack a pencil and crayons too!

Excellent for Elementary Aged Kids!
We bought a second after seeing how great this travel guide is so both of our elementary age kids could have their own. I will buy this brand of travel guide anytime we go anywhere they offer one. It is informative but also has lots of different activities. I highly recommend this.

Format: Kindle
This book is great for kids that already know how to read and it’s actually teaching them how to use a travel guide too. I like that kids can get away from their electronical devices. Could be great for homeschooling resource even if you don’t plan to visit. I downloaded 3 guides until now: Los Angeles, San Diego and Washington, DC (the latest). My kids enjoyed each and every one of them. I plan to purchase the physical books also
