It depends on how fast you are, and if you get lost like texplorer and dan ("fit party of two under good weather", well with a little fog too) and end up climbing a new route or not.
i mean - some "fit and strong parties" can round trip the route in less than a day return from Squamish. other "fit and strong" parties will require a bivy or so. more if you get lost on the descent and make an illegal reentry to America.
As for the pocket glacier, a few weeks ago it had almost all slipped off. there MIGHT be some ice fall danger still but there is no way you'd need crampons or an axe.
