I've done the Hakone Loop. It's kitschy, but kind of fun, and you do see some nice scenery, although it's anybody's guess if Mt. Fuji will be visible on any particular day.

Since you will be following the same sequence of transportation as everyone else, there's not much chance of getting lost.

It's been a while since I was there, but I believe that the ticket office where you buy your tickets for the Hakone Loop has maps in English.
