I fully plan to place my order for a Nikon D40 with 18-135mm lens within two weeks. I went ahead and ordered two SanDisk 2GB Extreme III cards over the weekend as they were a great deal. I guess my question is will these two cards be enough for family stuff photos and the occasional trip to WDW or a Disney Cruise, assuming I download the images after the various trips or family activities? I would say with our P&S camera we normally dont rack up more then a couple of hundred photos on several day trip.
