I skipped Marys Peak because I had done that one already, but with the gate open on Prairie my brother and I did the other three starting from Corvallis in about 9 hours while taking our time sightseeing and stopping for lunch in Veneta.
We started at 9am and finished around 6pm, so there was plenty of daylight left over, yeah four should be easy.
