I am out of town on business this week, and when I looked at the description of the Millennium Harvest House Boulder hotel. In the description of the room it said that they have data ports. What they don't clarify is that their data ports are phone jacks. It has been such a long time since I had to use dial-up.
To be fair, the hotel does have an 802.11b network in the lobby, that is available for free.
