Dear 100 Hour Board,
As a follow-up to Question #90933, which temples do still have escalators? Is it only Seattle, or are there any others?
-Need to make new plans...
The Provo, Ogden, Jordan River, and Seattle temples all had escalators in them originally. Those temples were built around the same time, and with similar floor plans. Seattle is the only one left of those four that still has escalators. I obviously haven't been to every temple in the world, but a quick Google search showed no evidence of any other temple having escalators. So it might just be Seattle at this point.
I tried searching the archives for "temple escalator", but the only thing that came up was Question #76607, which mentioned the escalator at the North Temple train station in SLC. So there's another option for your wedding if Seattle is too far away, I guess.
