It sounds like you need a service like hotspotvpn which encrypts and tunnels your traffic until it's well outside of the hotel's network.

Hotels aren't exactly known for secure networks anyway, and a vpn service is primarily there to protect your traffic from other guests or the hotel itself from snooping on your usage, but routing all of your traffic through a 3rd party service would fix your filter problem too.
