This has nothing to do with Autodesk software but thought I would write it down at least for my own benefit as I have not seen this solution mentioned anywhere else.
When joining the hotel WiFi with my Mac I'm not redirected to any webpage, so I cannot log in, which means I don't have internet access. :(
When I was looking around in the System Preferences >> Network settings to try one of the workarounds of removing DNS servers or adding the google ones, I saw that a DNS server has automatically been added.
I went to that IP address in my browser, and voilà!, the log-in page came up :)
Maybe this only works with this specific WiFi, but could be a generic solution. In case of many other WiFi's the log-in page IP was simply 192.168.1.1
