I have two digitals but will take the smaller/fewer function one with my to WDW. But I love both of them.
My smaller point & shoot is a Canon A75 (they've had several upgrades since I bought it) and it takes great point & shoot pictures. It has a full auto-setting with lots of scenery modes (landscape/outdoor/night/action/etc) as well as a manual mode.
I also have a Canon S2 IS that I absolutely love. I really want a full digital SLR but haven't jumped into that yet. But with my S2 IS, I have attachments for to use other lenses on it (telephoto, macro, etc) as well as filters. I use lots of manual settings on it (it also has full auto). I consider it a "point & shoot / SLR hybrid" - it does a lot more than point & shoot and I can use the lens & filter attachments, but it can be a point & shoot. Because of my attachments and optional equipment, it is a pretty big camera bag and more than I want to deal with at WDW. I could disassemble everything and just bring the camera itself (it works without all of the attachments) but since my smaller Canon still takes great pictures and can fit into a small bag easier, I'm bringing it (and if something happens to it, I'd be a lot less heart broken).
I've been extremely happy with every Canon digital I've had.
