I have a way that I normally visit the different resorts. I take the bus from my resort over to MK, then hop on the monorail and make stops at Contemporary, then the Polynesian, then GF. I head back to the MK and take the boat to WL and check that one out. Then, I go back to MK, and hop a bus for Boardwalk. Then I just walk around the lake and check out Boardwalk, Swan/Dolphin and then over to the Yacht and Beach Clubs.
If you want to do more of the resorts, you could take the friendshop boat to MGM, and hop on a bus to say, POR and then you can check that one out, and then walk over to POFQ. Then, you could take the boat to DTD, and hop on a bus to the AllStars.
Wow...that would make for a long day wouldn't it??!! As for the others..POP, CBR and CSR..you could just take the bus from the different parks and visit each one individually. AKL is best done via the AK buses...go to AK, hop the AKL bus, and then back again, unless you take a different park bus from AKL. I don't do them all in one day....I usually break it up by sections. Have fun!!
