microstation & geopack classes

Bentley offers online classes. The ones you want will cost you, but there are a few free ones. You can take either instructor-led or self-paced classes. If you choose to take the self-paced you can take them at your own pace and on your own schedule. I think they have manuals you can purchase also. They also sometimes have physical classes in a city near-by, but I doubt you can find one on a weekend. Go to bentley.com for more information. Axiom International also has online courses.
