Announcement Blurb: The dates for the summer study are July 11 - 20, 2021 and we are now soliciting site proposals. Send site proposals to cushman@umn.edu by November 15, 2019 and they will be evaluated by the entire DPF executive committee. Plan for ~ 1000 attendees. Include the following: Names of your local organizing committee, cost and availability of lodging (mix of low- and high-end hotels, dorms or retreat center), public transportation, rough estimate of registration cost prior to any supplement provided by DOE or a private foundation, although your plans for defraying the cost can be included. Include parallel session rooms, auditorium (seats ~ 1000), coffee breaks, AV, and administrative help. Provide a rough estimate of banquet or reception costs separately. Feel free to include any special advantages of your venue. For your reference, the 2013 website is still (mostly) available at http://www.hep.umn.edu/css2013/
Process: Steering committee and program committee reviews, but final vote is DPF exec only. Each page has the proposal and a list of pros and cons. Everyone is welcome to fill out pros and cons for each site as a way to begin the discussion. Direct comparison of budgets was examined by Tulika Bose and we will have to ask for further information from the sites, so don't worry too much about the budget details; instead think about other costs, like getting there and cars and hotels and lunches. Consider the site, the organizing committee, your personal preferences - whatever you want, since these are just talking points.
APS has software they use to choose sites. Here is relevant information from that software (as promised). Availability of convention centers is not relevant, so I left it off. comparison table
