Okay we are having some fun now.
Based on questions 1 & 2 sounds like you don't really need a lot of manual control but may like to use program modes that give you some creative control over how the camera sets exposure.
You would like to learn to take better pictures so this is where I once agian plug the sites
Kodak't Photography Tips and
Photo Tips for WDW at Deb's film or digital these sites make more differance in your results than any camera will.
The next two questions flirt with conveniance of use and experiance. Sounds like your prior experiance stank and so you didn't use the camera. So not much to learn form that. You want at optical zoom most likely least 3x .
No computer or cable phobias so the docking station thing doesn't sound like a good use of your money, you are just as comfortable with a USB cable.
Camera size wasn't brought up so I assume it isn't a real big deal.
Here are some thoughts:
2 mega pixels will make an acceptable 5x7 t 8x10 # will give you a little better qaulity and more likely more room to play with the pricture in the PC before you print.
If you don't have a CD burner I would get a 2 mega pixel camera and a CD burner with the buget for a three mega pixel camera becasue you need to be able to archive pictures in a failry stable format and CDs are it. (see Zurgs manifesto at Deb's)
What ever you get you will need more memory and maybe batteries.
cameras:
Fuji 2800 Zoom. Fairly basic feature set but it has a 6x optical zoom. So if you like getting in close without being close that zoom is way cool. This is a great little camera but it doesn't have video out and Zurg loves to see his pictures on the TV in the hotel room befor he goes to bed and this puppy doesn't do that. The 3800 is just coming out and is a 3 mega pixel version of the same camera but still no video out.
Hello Mr. Fuji - Zurg thinks you made a mistake this would be his most recomended camara if it had video out. (anyone think Mr. Fuji cares what Zurg thinks?)
Sony's Cyber-shot DSC-P51 P-51. I think Glo just got one of these. Nice little camera, good dark situation auto focus system but only a 2x optical zoom and that is an issue for me but maybe not for others. The Sony Cyber-shot DSC-P71 has a 3x optical zoom and more mega pixels for more moeny. These two take AA batteries and that is a big plus in Zurg eyes. Sony's auto focus system is very good in low light and is a plus.
The Canon s30 is a very nice camera. Nice features. It uses a proprietary battery and that can be an issue as you can't cheaply get extras.
I am an Olympus fan and have had good luck with their camreas going back a whole lot of years and rolls of film. (My DD now used my Olympus OM2 SLR and I just made her an old fashioned film dark room). I think the 3020z is a nice camera with a full set of controls maybe more than you will use.
They have a nice mini camera the D40 a 4 mega pix pocket size job. I have a c700 the 2 mega pixel version of the 720 you looked at. These cameras pack a big zoom and that is what I wanted (not just for BadShoe.com but for taking pictures of the kids they mug for the camera and I like to sant off and zoom in) but there is a funky "cromic aberation" issue that puts a purple fringe on stuff that can be annoying. You should know about that going into the big zoom cameras.
Nikon makes great cameras also know as Nikons (well with the exception the entry level digital stuff. I don't like the idea of no viewfinder.) The cool pix 4500 is the current version of the Nikon swivel body camera it has a 4x optical zoom but some of the older versions may still be available. Our good pal Dan Murphy uses a Nikon to great advantage. They are full feature camaras and have a great reputation. The 4500 is pushing into the advanced "prosumer" level camera (Canon G2 Sony DCS s85) and these may be more camera than you need.
The minolta 304 / 404 cameras are worth noting for the lens quality and 4x zoom.
Go to some stores and play with some cameras, feel them in you hands. Push the buttons. Do the Zen thing.
Let us know what your next questions are.
Now you will have to have two accessories for most of these cameras to do WDW. 1) more memory 128 meg card and 2) rechargabe AA batteries.
