Is it ever good to have double spreads throughout a book?

[MOO]

I've been doodling around with a prompt for a scbwi Illustrators day Conference coming up. We are to do three pages illustrating part of a song. I really want to do some detailed colorful pictures in the ocean but I keep thinking that we need to vary the pages so it will be more interesting. But does it work to have all pages illustrated-no spots, not onesided pages, etc?
