yes, we use the stairwells all the time, especially in the early mornings, to get to HS. Last trip, we were in the opposite wing of HS, extra steps for sure, and kids often opted for the stairs, while I found the elevator a better option. But yes, definitely can make good use of stairwells, for avoiding waits at the elevator, etc. love taking the stairs out and around the pool, or down at the farthest end when going/coming from HS
