Yesterday, I reported to the tour group that I would travel today, but I can't go today. Do I have to pay the travel fee?

It depends on how many days you travel. Generally speaking, a one-day tour group, if it doesn't involve meals, is too sudden if it is for your own reasons. If it is based on a tour bus, (there are 5 people going in a group, so you have to book a car with 51-55 seats, and if you don't go, the fare will still be shared), so the meals or the expenses of scenic spots and tour guides will be deducted.

if you just sign up without paying the fee, you don't have to pay it under normal circumstances.

However, if it is a group that travels for a few days and goes out of the province, if we leave tomorrow and talk about it today, we may be able to refund you the meals, accommodation and scenic spots, as well as the fares. For example, some non-refundable (big transportation expenses: plane, train and ship) have been paid by the travel agency and cannot be refunded. If there is a problem with air tickets, under normal circumstances, the travel agency has booked them relatively cheaply, so it is not allowed to sign and transfer them. However, there are exceptions. If you negotiate with the airline, you can refund the ticket, but you have to deduct the formalities fee, so the money returned to you is relatively more, so it depends on your situation.
