Registration and Hotel Reservations

Your acceptance email will provide a password to register online, pay your registration fee online, and reserve a room.


Registration fees are $400 per person. Everyone, including organizers and invited speakers, must pay the registration fee. It is refundable if attendance is cancelled. No food is included in this fee.

Hotel Reservations

A lodging package at Aspen Meadows Resort is arranged. The 2020 nightly prices include a full breakfast and are $142.50 per person for a room shared with another person or $259 for single occupancy. Reservation instructions are available only after the application deadline has passed and will be emailed with acceptance letters, about two weeks after your application deadline. Regardless of which hotel you choose, please be mindful of their cancellation policy. At Aspen Meadows Resort, deposits are non-refundable if cancellation of all or any portion of your stay occurs fewer than 30 days from arrival.

We do not block as many rooms as there are participants in a conference because many people share. The available rooms are on a first-come, first-served basis. If the room block is full, you may not be able to get a reservation at Aspen Meadows Resort, or may have to pay a premium price, so BOOK EARLY. You are welcome to shop online for other rooms in Aspen.

Shared Hotel Rooms

A limited number of rooms are available with two queen beds. Additional rooms are available to share with one physicist in a king bed and another on a pullout sleeper sofa.

You will have the opportunity to enter your name or find another name on a roommate list, should you elect to share a room. If you plan to share a Meadows room, instructions on making a reservation will be on the registration page.

PLEASE NOTE: Some conference participants have reported receiving phone calls or emails regarding setting up hotel registrations through an "e-hotel" service. THIS IS NOT THE ASPEN CENTER FOR PHYSICS and we will NOT call you for a payment. Lodging and Registration are handled by the Aspen Center for Physics. If you are accepted to a conference, you will receive an email from us with instructions on how to register and book your hotel room in the conference venue.
