Wonder Thrills

So I am still struggling with this whole titling my book thing. I really don't want it to sound dumb (obviously) or too cliche. And I am just really blanking on ideas. I am not sure if I even really want a title. I am thinking at this point that I might just make one of the photos that has a sign in it the cover and basically making whatever the text of that sign is the cover.

Right now on my booksmart thing on my laptop I have this as the cover, as a wrap around:

So maybe it will just be called "Wonder Thrills" -- or this will just be the cover and I won't really have a title.

I just like that the arrow would be pointing into the book and whatnot. I have another photo of this (not easily accessible at the moment) where the sign is lit up -- so that could be another option, but I kind of like how this isn't so flashy and in your face.

So yeah, that's where I'm at right now. Let me know if you have any better ideas for a title for me, I'd love to here some of your ideas!
