depends on what you're looking to do.. just look around? then go over to grand floridian look around, hop on monorail, look around contemporary, hop on monorail, look around poly..
best arcade is at contemporary..
mizners lounge at grand floridian, tambu lounge? at poly, outer rim? at contemporary...
or go over to the boardwalk area and walk the loop and catch the boardwalk, swan, dolphin, BC/YC.. ESPN club is on boardwalk along with lots of shops.. nightlife-jellyrolls on the boardwalk..
just a few ideas..
