We have lunch reservations at Whispering Canyon and then will be heading from there back to our room at the Polynesian for our son to have his nap. Is there a boat that runs between the two, or do we have to go back to MK or the Contemporary to pick up the monorail (or a bus or boat from MK) to the Polynesian? I'm a little rusty on my Disney... And it has only been a couple of years!
