Is there any way to go to Macau by myself without joining a tour group?

It depends on the type of visa you apply for. If the visa is applied for in a provincial capital city, you can travel freely without going with a group. If not, then you have to join a group at the port, which is actually a free trip, but you have to go through the group channel. The cost is about 50-60 per person.

Generally, the pass cannot be applied for in places other than the place of residence.
