I think someone posted this a while back and the ideal is something like an 18-200, but since you don't have that, I would definitely have the 50mm for the indoor shots (Donna's advice is spot-on). We went two years in a row and I do not have a fast lens, I hated relying on my flash recharging and I hated using a flash, period, for the character photos. Some of the dinners (particularly the princess dinner in Akershus) are crowded and fast, and the characters come by, your kids stand up, and click-click, you need to be done. (I didn't want to be one of the loud, obnoxious tourists who took forever with their cameras.) I kept my camera on my lap, ready to go, and took the shots as fast as I could. We occasionally got a "thank you" from a cast member regarding efficiency. If you're in the parks after dark, though, like Donna said, it's great to have a low-light lens, the atmosphere is so wonderful with the ambient light there at night.

I didn't find myself taking many zoom shots at all, wide-angle was more important. I did want a long lens in the Animal Kingdom for the safari, but if I needed to weigh one against the other, you can get close-ups of zebras at the zoo anytime, but that shot of your kids with Mickey and Minnie, those are pretty rare.

If you have a P&S you could take, Donna has a great idea. If not, I'd keep the 50mm on when you're inside eating, or inside with characters (like at the Character Connection in Epcot), and put on the 18-55 when you're walking around.

But that's my two cents! FWIW.

HTH!
