We love our digital camera. We have an Olympus D-460, a 1.3 megapixel with enough memory for around 160 pictures. Plan on lugging along a laptop for storage of your pictures.
But it was very nice. The laptops come along anyway for hubby and my jobs. We'd snap photos all day without worrying about using up film or processing costs, download them in the evening, the kids would get to see them immediately, and start the next day with room for 160 more photos. We haven't had any developed into physical photos yet (my parents had their camera with them and I have copies of their photos), but when I do get my pictures developed, I'll only pick a dozen or so really good ones from the entire trip. (I develop photos once a year now and give a package out to relatives for Christmas).
