I'd suggest not having the whole background as the wood effect -- it'll be much more effective used as an accent. Maybe a strip of 1/3 the width of each page down the outside edge?
As an exercise, try picking a couple of different sketch inspirations and to a rough layout based on them even if you don't think it will work -- it'll probably spark some ideas.
And play around with titling and journalling -- if this was such a great tour then you must have something to say about it!
