Thank you for taking the time to answer, but you completely ignored the parameters of the question.
I didn't ignore it, I just disagree with the limitation you've set for yourself...it seems silly, to me, IMHO, to only take (1) 1 GB stick and expect to get all your pics on there and then worry about if you have enough storage to save the files...which I still recommend you take at the highest resolution and quality settings your camera offers regarless of your print size intentions or the size of your memory cards (or card in your case).

IMO, it's better to take 4 1GB cards then a single 4GB card just because those things are not so reliable, secondary reason would be speed of download.
