Going Up, or Down or ??

Apparently, spring has been busy! Sorry for the lack of posts, but I've got a bunch of fun things to add here.

This elevator panel was spotted on a ferry near Seattle. On my way up to the passenger deck, I spotted this amazingly annotated panel. Was it really that difficult to get from 1 to 2? How many passengers had difficulty with this concept? From home made labels to sharpies, apparently there was a good deal of confusion of just how to get from level 1 to level 2. Going up?
