in my opinion:
*boat at BWV to epcot and DHS > buses at OKW
*buses at OKW to MK and AK > buses at BWV to MK and AK
the boardwalk is a fun area though if you budget some free time to hang out and watch the performers (jugglers, magicians, sword eaters...)
OKW is a great resort and the 1BRs are about 1000 sq feet...some posters are a fan of the king bed in the 1BRs and the associated "nookie perk" that the wall between the bedroom and living room provides.
either one is a good choice, just depends on your personal preferences...
