I am going on vacation too very soon ( Yellowstone ), My solutions is, buy an extra card ( 4 -8GB cards total ), andshoot S-Raw-1.I tested with my finial output 8.5"x11" and could not see any differance between RAW and SRAW1. I can get twice as many pictures, from 20Mb down to 10Mb, until I reach the last card, then switch to JPG, which should hold over 1000 images.


That sould be a total of 1500 SRAW1 images and over 1000 JPG, I only took about 1200 images in Colorada last year.
