Breezes is next door to Palms on a lovely beech... Personally I would give stone town a miss its filthy and full of robbers I wouldnt go there with your camera and a big lens if you know what I mean

Actually, Stone Town is pretty safe. It's much safer than any other city area you will find in East Africa. I walked about there with my 30D and 24-105 on all day and didn't feel even the slightest bit threatened. Now, things do change dramatically once it gets dark. I would NOT venture out with anything expensive after dark. During the day you should be fine. Be smart.
My wife forgot her camera at Mercury's and when we went back it was still there. You can't say that about many places in North America, even.

Actually, nice math skills I have. I have 42gb of memory. 5 x 8gb cards and a 2 gb card.
I can get over 800 pics with my 30d per 8gb card, so that's 4000+ pictures. That would average 450 pictures a day, I think that's lots, If not, I'll switch to jpeg after the first day. I am out of cash at this point, nothing in the budget for a hyperdrive.
Here's a question, what do you do if you have to go to the bathrooom when you are out in the parks? Sound funny, but really... strange foods, travel, jet lag...can all add up to an upset tummy>
You should be fine with 42GB of space. If you find yourself running low, you can always browse through images and delete ones you don't want to keep to make space. The Breezes in Zanzibar is an amazing place. You also can't go wrong with the Serena chain of hotels. They are also pretty top notch.
As for the bathroom breaks while on safari.......go quick and check your area first. Normally I would suggest a nice bush or treed area.....but you would probably be a lot safer going in an area where you can see clearly around you. Also, having and extra pair of eyes wouldn't hurt. Hope you don't have a shy bladder 
**EDIT**
Don't forget anti-malarials. It can take anywhere from eight days to a couple of weeks before any symptoms set in and it usually only seems like a fever or flu. A lot of doctors in North America won't think of doing a blood test for the parasite. It can be fatal. Oh, and like breathtakingbluesky mentioned: IMMODIUM is your friend!!!
