Travel agency related issues

There are things to attend. What group?

Generally speaking, if it is an empty group, it will not work. Even if you can, you have to charge more, because most of the tour tickets booked by travel agencies are special fares, so you should book them in advance. If you join the group temporarily, the ticket will also be issued temporarily, and the price will be a little more expensive, so there may not be a quota.

If it's go on road trip, it's generally ok. Your company is a package tour, and the number of people is subject to the number of people getting on the bus that day. If the number of people doesn't change much, you can make it up, but you'd better call the regional travel agency to ask about the parking space of the bus tomorrow and see if there are any extra seats for you to make up!
