I've never taken any of the classes out there. I'd recomend calling ahead to make reservations and find out there schedule.
I think all the one day classes are single pitch climbs versus multi-pitch climbs, but I'm not certain. There are some pretty nice scrambles across the top versus outright climbs availible as well that you could take on without the school if you are feeling spunky.
Can't go this weekend but if want to do it again later in the year let me know. I've got a couple of 60 meter climbing ropes in decent shape, a couple of harnesses and some gear. I'd be up for a scramble and maybe a bit of goofing around repelling, but I'm in no shape for a real climb.
