if the pp decides to use that hotel, check out the 'free' part before booking.
some hotels might have free shuttles but you need to find out what are the times these shuttles run.
one year back in the 90's i stayed off site.
the hotel offered free shuttles to the park.
but, there were only 2 shuttles for the morning.
9:00 and 10:30
for the return with that hotel, the shuttles ran only at 5:00 and 7:00 pm
we did it for one day and then rented a car ....
