Booking a hotel online was originally in 400 yuan. Why is it much higher when paying?

When booking a hotel online, there may be several reasons why the price is higher than expected when paying:

1. The hotel has added some taxes or insurance, or there are other service charges, resulting in an increase in the total price.

2. When choosing a hotel, you may choose a higher-priced room type or service, resulting in an increase in the total price.

3. There is a situation where big data is "killed", that is, the same hotel and room type, and the price seen by old customers may be higher than that seen by new customers. This is because OTA (Online Travel Agency) generally offers lower prices in order to attract new customers, but offers less concessions to old customers.

Therefore, before payment, it is recommended to read the price details carefully to confirm whether all necessary fees and services are included. In addition, if the price is abnormal, you can try to contact the hotel or OTA customer service to find a solution.
