The current list of people looking to share a room can be viewed here: https://docs.google.com/spreadsheet/ccc?key=0AjaRXl4XWh2QdERMemdUMGtJRXlaZnpqdXpjd3o0cVE
Things to specify in the comments section:
* Number of people you wish to share with
* Preference of male/female roommates
* Any other information you feel is pertinent
If any of your roommates will be arriving separately, be sure to list their names on the reservation as having permission to check in and get a key to your shared room from the front desk by showing photo ID.
When reserving your room, be sure to specify the type and number of beds! Some rooms only have a single king size bed; not ideal for platonic room sharing. Cots may be available, but they are not very comfortable.
