The hotel’s internet is perfectly fast. It is also perfectly Chinese. The Great Firewall applies on a Marriott network in China exactly the same as on a ¥80/night guesthouse network. VPN still required. For full internet context: Internet Survival in China.

The Two Problems With Hotel Wi-Fi in China
Problem 1: The Firewall still applies
This surprises almost every first-time visitor. The hotel network is not exempt from China’s internet restrictions. An international chain hotel in Beijing has the same firewall as a local internet cafe. Your VPN must be active whenever you want to access Google, Gmail, WhatsApp, Instagram, or any other blocked service. Install and test your VPN at home before departure. Guide: Best VPN for China.
Problem 2: Network security
Hotel Wi-Fi networks in China have been documented as targets for man-in-the-middle attacks, where malicious actors on the same network intercept unencrypted traffic. This is not unique to China (it happens on hotel Wi-Fi worldwide) but is worth taking seriously. The {ext(‘https://www.ncsc.gov.uk’, ‘National Cyber Security Centre (UK)’)} advises using a VPN on any public or shared Wi-Fi. With a VPN active, your traffic is encrypted and this risk is effectively eliminated.
