Everything. The minute we get there we are ignored for a good 15min while the front desk flirted with a girl in the lobby. We are finally helped, but with attitude from the minute I opened my mouth to check in. Then we were told I had to have a passport to check in. I provided my out of state drivers license and was told that still wasn't enough. They had to have an itinerary showing that I planned on leaving. Nothing on the website we used to book advised anything about having to provide a passport and i have stayed at sevreal hostels around the US and never once did they require a passport to stay at their establisment. I even double checked my itinerary details when we left to see if there was any disclaimer. We ended up just cancelling our reservations as long as they didn't charge us. The guy checking us in was rude the entire time and had little to no care if we stayed. Never again.
