Activity Guides and/or GT Forms

I am wondering if Activity Guides and/or GT Forms would be good options to use to incorporate into the Travel and Expenses modules to assist users when entering travel claims. We are currently on Image 33 and version 8.57.09. I could not find any information where either option has been utilized for training purposes. We working to find option that will assist our users while they are entering data on expense pages. Any information that you can provide will be incredibly helpful.
