I think the solution was to use opendns servers in /etc/resolv.conf.
The reason it works is that, according to the article I read, many of
these captive portal systems work by not giving you a dns server until
you enter your credentials. If you manually specify your own dns
server, you can avoid entering your credentials.
I've never tested it, but I know that the captive portal systems I've seen give you an IP
address before you enter your credentials. In fact, they have to give
you an IP address otherwise you couldn't get to the "credentials"
webpage.
