prices are provided by supply and demand.
When equilibrium is broken it will be finding a new one.
In my opinion prices have already being inflated and I am not sure how much an expensive Thailand is attractive at tourists eyes, considering that the service quality stays the one of a cheap destination. It actually worsen due to covid and people being fired.
This will benefit mainly expensive hotels where customers do not really care spending 8usd more per night, but it will be not great for hotel who target price-sensitive customers (which are the most in Thailand).
