2. If you have other losses, such as you made an appointment with the wedding master and paid a deposit, then the wedding didn't take place as scheduled, you can ask the hotel to compensate you for this loss. And other losses you spent on the wedding, etc. You can claim compensation from the hotel, but you must have relevant bills and other evidence.
3. You can also claim compensation for mental damage from the hotel. Because a breach of contract like a hotel is enough to cause your mental loss.
