If you get a fun server, they do fun things around asking for ketchup, straws, and soda refills. There are also games for kids (sometimes) and newlyweds.
From the Poly you have several options.
You can take the Poly/GF boat or take the monorail to the MK, then switch to the WL boat. Or you can take the monorail to the Contemporary and take a boat from there. I would guess the first option (switch at MK) is the fastest.
