sorry none.
most offsite will go a couple of times in the morning
there return times generally start around 4pm
sometimes the last return time is before the fireworks.
you will spend more on taxi - than you would just getting a rental car.
so plan with the rental car.
now the exception is the DD hotels
www.downtowndisneyhotels.com
but they are as expensive as the value resorts -some get up to the moderates.
the only EMH is with Hilton, generally the more expensive of them.
no airport transportation - so again something else you will need to pay for.
now I do love offsite (and onsite) - but you definitely need a car for offsite.
here is a schedule from best western lakeside
http://017b588.netsolhost.com/shuttles.htm
if you miss their bus - you need to take a taxi - it does not come back
the schedule can change - so you need to be at the stop at least 20 minutes before the bus is due - it may be late it may be early.
so even trying to take the bus for offsite can be pain
if the free transportation stops at other hotels before it gets to yours (and many do) then it might be standing room only - if you get a seat then it might go to other hotels before going to the parks.
one of these offsite buses goes to at least 10 other hotels before going to the parks.
go to the tranportation board - they can help you get a good deal on a car rental.
