Reservations must be made by 5-7-2026.

Given that summers are extremely busy in Boulder, we have contracted rooms for guests to stay at the Hilton Garden Inn. We request that you make your reservation at the link below or by calling Hilton directly and sharing the group code (90H) with them verbally.

While we have contracted enough hotel rooms for June 6th and 7th, you are welcome to book additional nights so you can stay and explore Boulder! Pending availability, you can also book using this room rate for up to two nights before and/or after June 6th and 7th. For example, you could book from June 4th through June 9th at the discounted rate if Hilton has available rooms. But anything prior to or following those dates would be at the normal rate.
