It really depends on when you are traveling. Our daughter uses a wheelchair and can’t get out for transfer.
Miller Road is our favorite location and we usually stay there twice a year for long trips.
We have very seldom ended up having to wait for a bus because either all the spots are full or the bus is too full. We are usually not going to the park for park opening though - usually more mid morning.
The last stop at OKW is Hospitality House; we
have been on the bus when it was too full for any guests in wheelchairs or
ECVs to get on there, even during midday when it was not very busy.
The first stop is Peninsular; if you are trying to get on the bus there at a busy time for people coming
back to OKW from a park, it will sometimes be too full to get on. When we are returning to OKW, we often get off at Peninsular because Miller’s Road is a less than 10 minute walk and we can clear out the bus for other guests.
Worst case scenario is that you miss the first bus and the driver will radio for another bus.
