This is a great alpine climb, big too. We took a leisurely pace choosing to complete it in 5 days. Summited on the 4th and hiked out from Camp Sherman the 5th. Cold and snow on the first and last days. Almost all snow climbing. Advise getting to the ridge on the climbers right side of it. Didn't summit Rainier, just Liberty Cap. Whatever, I'll get it some other time. It's an alpine route but can be kept reasonably safe with pickets and ice screws.
