I booked a seven-day hotel chain in Beijing, and I paid five days in advance. But I'm only staying for four days. Can I take an extra day off? Why don't you return it?

You can return it, I'll return it to you at the front desk, or you can pay the accommodation fee for one day;

If you travel to Beijing, I suggest renting an "electronic tour guide" to find a wonderful and comprehensive tour guide. Inquire about the bus and subway anytime and anywhere, and tell everyone how to take the bus so that everyone will not get lost; It is convenient to find snacks and restaurants by GPS. .....
