I know a lot of lifties- the snowboarders will sometimes leave their boots on but skiers will always swap out, it's just not safe to wear them when you might have to book it to save some asshat from themselves. Besides, the lift shack heater should keep your ski boots warm, dry and soft for easy entry.
I'd get the warmest fkn winter boots I could afford for standing around and bumping chairs if I were you though. Waterproof is a must.
