We have consulted with the Hotel Manager. No matter where you ask for special pricing by lowering room rates from 8400 THB/night (where prices are discounted by 30% from the full price 12000 baht/night), only 5,000 baht/night, then we notice that they can't lower the price as you want. But we were allowed to reduce the price of the remaining 7500 THB/night. as a special case, only this time only because this is a time when the country is mourning for the loss of the King. So we don't want to stress it with other issues.
Please consider our proposal. Reply via email as a reference document would be grateful as well.
