Book- Along I-75

[Disney Ontario]

Hi, I love this book for our trips to Disney, All the Walmarts are highlighted. How much difference is there in every edition? Our last copy was the 14th edition, and I see there is a #15.

I am not sure how much is changed, however we always like to purchase the new edition when it comes out since it's the most up to date. So with that being said we already purchased the 15th edition a few months ago.
