the sheraton vistana is an outstanding resort, with really nicely done suites (they call them villas, but to me they're suites)..
dreams unlimited (the sponsor of these boards) usually has really low rates for the sheraton vistana, so you might want to check with them - though i don't know if you're buying a package deal from your agent...
however, i don't know if the sheraton vistana offers transportation to the parks or not....perhaps you could check this on the resorts board....or even put in a question to one of the Dreams Unlimited agents (and ask them for a quote)..
we usually stay on property for convenience....
by the way, i believe the price Wayne is quoting for OKW for free dining, also includes the tickets - so take that into account when you're comparing prices...
