Where can I book the National Day Hotel and pay at the store? Will the price increase be overcharged?

No, if the order says to pay in the store, there will be no extra charge.

Of course, you have to look carefully at the date, room type and service included in the order. Some include breakfast, and some do not. As long as it is stated on the order, the hotel will provide it according to the price on the order.

In addition, ask me if the hotel has stated that it can only be used by one person, because some hotels abroad have the difference between single occupancy and multi-occupancy
