ALso, hiddenmickeys.org has a lot of sat. photos if you follow the links to hidden mickeys at the given parks.
THe global explorer things is pretty nifty, but it is prettys potty outside the US and the fee to subscribe when the 30 days runs out seems to much to me! You can find the basic sat. photos on the net, just not with the nifty fying interface the global explorer program has - it doesn't seem worth it to me, ymmv-
