Hi Marcie,
I would suggest either 512K or 1GB memory cards. These are both larger than 256K. If you have your computer with you, you can buy the 512K cards and download the pictures onto your hard drive. If you don't have your computer, you should buy the larger cards. I have four 512k cards and four 1GB cards. I can use the cards in both of my cameras. On ROAR, I used them all to near capacity as I didn't lug the computer all the way to Africa.

You and Andrea can practice together on MUSH so you'll be an expert before the world cruise starts.
