ya they are runnin sightseein things/hiking. Last time I was there in the summer, they were lettin people hook their bikes up to the back of the chairs, so that might be available again too.
they are also serving dinner at the summit house, so you could probably get a job there, they always have a shortage of food employees, and its supposed to be more "ritzy" then just a daylodge/dining, you need reservations
