Sorry this is late but believe it or not I was actually at the parks and I was just too excited to write. Here's the tip, such that it is:
Photopass photographers. Disney's photopass personal are all over the parks, and often have some primo spots staked out. One thing you should know is that even though Disney wants to sell you on their photopass system (and although the prices are high there are sone good points too) you can ask any photopass personal to take tour picture with your camera. This means you can get the same picture of your entire family, including the one who normally is always behind the lens, for free. It is great and it's a good perk. We have seen photopass people take pictures with their cameras and a stack of cameras provided by the group being photographed. Give it a try!
P.S. There ate great Photopass write ups on several different sites.
