The hotel manager raised the price before the meeting.

Because the events described in the question are vague, they are probably printed:

1. The contract has been signed. Is the unilateral price increase of hotels a breach of contract?

2. On the premise of not breaking the contract, put forward to stop cooperation (just put forward, not really quit), and analyze what losses you will have if you quit the hotel from another angle. The analysis can be based on the fact that you are a professional training company, involved in business elite and hotel management. Try to persuade the hotel to rent out at the original price. Of course, the lobby rented at three times the price at the same time needs someone to inquire about the vacancy situation (there are few opportunities for vacancies during the Olympic Games). If so, it can also be a reason to convince the hotel, which is based on integrity. If there are other hotels with lower or the same price than the hotel, we are willing to rent the lobby of the hotel because we booked it in advance, although the hotel violated the rules. Remember, it is impossible to accompany the elite of 100 without some tolerance.

Even an efficient company can't change the meeting place, which is complicated, but if a company that trains elites works as a water fish for a hotel, is it still convincing? Therefore, we must explain a truth to everyone at the meeting. Honesty is the foundation (in fact, people are praised and derogated). In order not to harm everyone's interests, we would rather harm our own interests. This is still a big shortcoming, but the head is really going to explode. How many people who do business, especially those who do sales, have no black mentality? Alas ...)
