The total price for the rooms were only 66,500 Thai Baht in the proposal that I have signed and returned. However, your new proposal is at a higher cost. This isn't fair to us. I will expect the price for the package not to change. The hotel will have to accommodate my group at the same price. Please advise. I have attached the room arrangements. I will be expecting to pay the agreed price of 66,500 Thai Baht for the rooms regardless of the room types.
