I came across "open" WiFis that required another form of login inside that filtered all HTTP traffic but let through DNS. But no, it's not really useful outside of special circumstances.

I have WireGuard endpoints of UDP 53, 443 and a high random port - at least one of them tends to work (although not always — one hotel recently only allowed tcp/80 and tcp/443

How did DNS resolution work? Do they force you to use their proxy server?

They could set up a recursive dnsmasq on the router, and block udp/53 traffic to the outside world.
