For a similar reason I generally have my OpenVPN servers listen on 443/tcp. Client traffic looks like a https session from a web browser.
Hotels etc generally allow web traffic through unmolested. When operating on a site with a mandatory web proxy then simply use the proxy as well - if necessary via cntlm.
The main problem with tcp in tcp tunnelling is exponential standoffs making latency potentially horrendous but the general increase in bandwidth available nowadays makes this less of a problem than in the past. Maybe I ought to look into 53/udp instead 8)
