Sometimes when players encounter a map they don't want and there is one they like better, they can wait for it to change.
Now my suggestion is to have a little energy payment thing at the end elevator (except if the next map is "?" and Terminals of course (well it could be there but disabled, if that's more easy)) that lets the player spend like 3 E to spin to the next map instead of waiting for the clockworks to rotate it in. Basically a clockwork boost.
