I was just there last weekend and the snow was amazing but it was raining the whole time so watch out for rising temps... I would definitely recommend still skiing so probably buy a heavy duty poncho to toss over your stuff and you will have an awesome time.
We stayed at an Airbnb in glacier and skied friday/saturday then went on a super dope hike just around the general area on sunday (as well as watched the super bowl).
Chair 9 Pizza and Bar has super good food and is very close to glacier but for sure grab all of your groceries before you head to glacier.
Get the breakfast burrito at Mount Baker lodge! They serve them every morning around 9 and are suuuppppeeer good, definitely worth the $6 I think they cost.
Other then that just have a good time and make it over to Chair 1, if the under rope stuff is open just duck the rope and go ski that terrain because it is super cool.
