Do you have any problems carrying around your SLR? I just got a Canon SLR for my b-day and I'm scared to take it with me - what with sudden rain, jostling crowds, and wild rides... any advice?
The SLR is BIG, but you can't beat the picture quality and the ability to "snap, snap, snap" It is so nice not having to wait on the camera and to have the ability to take one picture immediately after another. I didn't realize how important it was until we went in January. Since DH wasn't coming, I bought a Kodak Easyshare, since it is small and easy to carry around. Well, when I was taking pictures of the kids with the characters, I had to wait several seconds between each shot. And with a 2 YO, it was hard to get a good shot the first time. I guess if I hadn't been spoiled by my SLR, it wouldn't had been that big of deal. But it seemed like it took forever.
Anyway, we have a large camera bag that we carry it in. We have 3 additional lenses too that we keep int there. The extra sizes are nice to have because if you have a lens with too big of a zoom, you can't get close shots. A lens with too small of a zoom, you can't get good pics on rides. Yes, it is a pain to carry it around, that is why I bought my small Kodak; however, I make DH carry it around

We've never had a problem with rain (and we've seen our fair share of it at WDW) or the wild rides. It's been on a total of 3 WDW trips and not once have we had a scare.
It is definitely worth taking. The year we went to DL, we had just bought a SLR 35 mm. DH didn't want to take it because he was worried about the same things you are. We regretted it the whole time not having it. Then we bought the SLR Digital right before our first trip to WDW and it has been worth every single penny and pain!
