We're open 24 hours a day, year-round.

Check-in is available from 3:00 p.m., and check-out is by 11:00 a.m. Note: Adults must provide a valid government-issued picture identification card (passport, driver's license, or state or military ID card) at check-in.


We accept cash, travelers checks, VISA, MasterCard, American Express, and Discover. A credit card is required for reservations (see cancellation policy below), but at check-in you can choose to pay with cash or travelers checks instead.

Cancellation Policy
If you need to cancel or change your reservation, at least 48 hours advance notice is required. If a cancellation is made without 48 hours notice, or if you do not arrive on the reserved date, your credit card will be charged for one night’s accommodation per person, and any additional nights reserved will be cancelled. (For groups, a different cancellation policy applies.)

Maximum stay policy
To better meet our mission as a nonprofit organization that supports travel and cultural exchange, HI USA has established the following maximum stay policy: No guest may stay at one hostel location for more than 14 nights in a calendar year.  Once a guest reaches their 14th night, s/he is not eligible to stay until January 1 of the following year. Additionally, no guest may stay more than 14 nights in any two-month period.
