Ok, I've been experimenting. First of all, my absolute favorite to use is my Kodak advantix. I never have any that don't turn out, unless I'm taking them of things I shouldn't with that speed film. I use 200, unless I'm trying to do any of the nighttime shows, as 200 will capture both dark and light very well, but the distance is too great for the nighttime shows. I've had the camera for about 4 years, and I never have to let them "keep" pictures when I get them developed (you know, when they don't turn out, you "sell" them back and don't pay for the duds). I highly recommend the high end Kodak advantix cameras. It did great in March and May!
My boyfriend took his Intel Pocket PC CS 630 in March, and I took it back in May as well. His pictures tended to have some lighting difficulties. This is a digital camera, but does not have a screen, so there is a limit on the number of pictures (over 200). It still did a great job, and was much better for the nighttime shows. Distance shots were not as good, and it doesn't have a zoom.
I'm taking my Kodak digital in August, so I'll review it at some point after that. It has been a great camera though, and I'm confident I'll get some great shots from it.
As for locations, we found some great ones!! MK, you need to get the front of the castle, as well as possibly the sides, where the rose garden is. The bridge in front of Splash Mountain is cute, with the falls in the background. The front of Space Mountain is good, framed by the building and sign, and as you exit the ride, there is a SM car to take pictures in, and ours turned out really cute!! In Adventureland, across from Swiss Family treehouse there are usually characters in a doorway, those were cute (we got Timon and King Louie!)
Epcot, you can get the ball from across the lagoon in World Showcase, there are lots of little niches to pose. Outside the gates also gives a good view, as well as looking back at it from the big fountain on the WS side of the ball. I got a great one of my boyfriend from the bridge between France and the gateway, with the Eiffel tower in the background. All the countries have excellent photo locations!
MGM, the Lilo and Stitch photo area, near the animation tour is adorable, and the lighting is good. The Monsters Inc area is cute but the lighting is not as good. A lot of characters were out to the left of the Great movie ride, and the blooming trees behind where they were made a great backdrop! We took several on New York Street, mainly one of him in the little Police cart out there. Near Honey I Shrunk the Kids, there's a bug's life display with "flik" and it was cute, with a good backdrop. In the play area, there are lots of good photo ops, and one I love is with the roll of kodak film, so cheesy! The Star Cruiser bikes outside Star Tours were also fun to pose on.
Animal Kingdom: Tree of life, and at the entry to Bug's Life there is a cute monkey, taller than my bf (so about 7 feet tall) and is cute to have photos beside.
That's all I've got for now, good luck and have fun!
