For all the information about travel, accommodation and food, check this page on the wiki. There, you will find the code you should use when reserving a room at Radisson.
Use this map to orient yourself or find alternate hotels, etc.
The directions to Sigma Xi are here.
Radisson will send a shuttle for you to pick you up at the airport if you ask them in advance. They will also run a shuttle between the hotel and Sigma Xi Center and take you back to the airport when needed.
Use that wiki page to find room-mates, to coordinate carpooling, etc.
The meals at the Center during the Conference are on us. Meals outside the Center are pay-your-own.
If you plan to arrive early, on Thursday, plan to join us for the Early Bird Dinner at Town Hall Grill - edit that page to add your name and to tell us if you need a ride.
