I've wondered about hotel hopping also! Can you just go around and look at the different hotels?

We're staying at POP, but I'd love to see AKL especially. It'd be great to see the animals.
Also, I've been trying to figure out the monorail system. At DL and DCA in CA they go through the park and to the hotels...so it's kinda like a relaxing ride sometimes.

But I've noticed in WDW it only goes to MK, around Epcot, and 3 hotels...is that right? So if you aren't at those hotels or going to MK are you allowed to ride? We're at POP, and going to Epcot and AK...so are we able to go on the monorail?
Thanks for any help!
