We are considering a trip in the next year or two. I haven't been to either park or done any research, reading, etc. since I was a kid. Where do I start??? There's so much out there. When there's tons of information, I often do best with a physical book that I can flip through, visually see chapter break downs, mark down pages, etc. Can anyone recommend their fav comprehensive book (there's so many!!!)? I tried to look at my library to at least get ideas of which I liked, but they have almost zero travel guide books for some reason!

I'm definitely open to websites as well, but I feel like sometimes those are more helpful when I already have a general idea and am gathering more detailed information, vs. starting from scratch.

Thank you!
