You can also try to change the DNS server to Google 188.8.131.52 or 184.108.40.206
If that doesn't work you can use a VPN (virtual Private network)
I had to use VPN when overseas and the foreign country blocked entry into Many US sites.
Being a Hotel, they contract out internet to another service provider (and that private company can block anything they want for any reason they want). DNS change probably won't work, but VPN should get you around their block.
