Can't delete pages in iPhoto Book!!

[shuffles]

I'm surprising my girlfriend with a 2 week holiday to Cancun in Mexico for her christmas present and I thought it would be a nice idea to get loads of pictures of the resort and cancun itself and make a hard back book in iPhoto to give to her. There are 20 pages in the standard book. I'm looking to get an extra large book. Is there a way for me to delete some of the pages or do I have to use 20? Don't think I'll find 20 pages worth of photos of Cancun!

Cheers,

Shuffles.
