Manual is often the best option. I worked for a company that was hell bent on automating a booking process and minimizing the number of humans involved until they realized how much many people preferred having a human guide them through different parts of the process.

They hired 100x as many call center workers as they thought they'd end up needing and sales skyrocketed.

My (largely younger, tech savvy) friends are always slightly shocked to hear this story - because they didn't appreciate having a human guide them.
