Here's an excerpt from the hotel's message:
Our hotel is currently over sold on this night. We will need to relocate 50 individuals within the PyCon group block. We will be relocating these individuals to the Spring Hill Suites and Quorum Courtyard. These two hotels are located about .5 miles from our hotel.
We will be providing shuttle transportation from these two hotels to our property for the days and times needed. Manny Soto, our Director of Event Planning and Operations and [Heather Halsted] will be calling the 50 Individuals directly to let them know which hotel they will be staying at.
Unfortunately there's nothing the PyCon organizers can do about this. If you're one of the relocated individuals and relocation would be difficult for you, please call the Marriott Quorum (sales: 1-972-855-5785; toll-free: 1-800-811-8664) and ask to speak to Manny Soto or Heather Halsted, or Jolyn Edwards, the Director of Sales and Marketing.
