An old style proxy that works at the http layer in the network stack will be fooled but I haven't worked with that dead tech for 15 years.
VPN is the best method.
Often hotels will just use opendns, if you can override the dns on your device set it to google dns and that will bypass opendns.
Open dns is so simple to setup and its free, you just make a simple change on your WiFi router, that's why some hotels use it.but more often hotels have managed WiFi and they have a better infrastructure.
I do this for job, so i am not just a punter who has tried a few tricks.. But it's great to see people trying tricks and sharing.
