Is there a difference between a group tour visa and a free travel visa in Europe?

Hello, I'm glad to answer your question.

A group Schengen tourist visa is different from the individual Schengen tourist visa you apply for. If you join a group, the type of visa you get is called Schengen ADS Team Tourist Visa. With this visa, you can't enter the Schengen country alone, but you must enter the Schengen country with the tour group. At present, most travel agencies in China stipulate that you can't leave the group during the whole journey.

I hope my answer can help you.
