I am a huge picture taker and love to scrapbook! This will be my first visit to WDW with my family (DH, DD8, DD5) and know i am going to crazy...my DH calls me the pix nazi! My sony cybershot has a 256 mb card and can hold about 125 pix (on a 3.1mp setting). I know i will need to buy another one, but will I have to buy more than that? From what I understand the 512mb card doesnt work with my camera. So, for all you crazy pix takers, let me know approx. how many pix you take on a 6/nt 7 day trip! Thanks much!
