We're heading down to Florida for two weeks in May/June, and I have an HP 8MP camera. I've only been to Disney once, and only for one day, and I took 300 pics. I take lots of pics on vacation and am going to need a lot of memory cards. What do you all do for this, it's a great expense to buy all of those cards, but I want to take as many pictures as I would like. Thanks!
