Around the parks they have little signs that say Kodak picture spot. If you look out for them and take pictures near there your pictures will look great. There is also normally a photopass person near there!!!
Hey! I recommend getting pictures in front of the many cool ride sculptures, as well as pictures with the characters! One great photo spot is in front of the Finding Nemo display near Living Seas in Epcot. Take lots and lots of pictures- your best bet is digital camera. Also remember years from now you won't care about those 50 pictures of the castle you took as much as those of your kids- so take lots of pictures of your little ones having fun! enjoy
We've decorated an entire wall with photos from the safari and two 'walking safaris' (sorry, forget what they're called) at AK. Also at AK, the walkway between Africa and Asia offers great views of the Tree of Life, as a backdrop or as is.
