Booking Hostels

Just booked rooms at 2 hostels for my trip. Can't believe how quickly it's coming!! I'll be at the Elephant on the Moon while I'm in Krakow (thanks Hillary) and the YMCA University Hostel for my last few days in Bucharest. Now just trying to hash out whether or not I'm going to fly to Krakow or take the train. The train route will take at least 24 hours and 5 changes, where as if I fly, it's only a couple hours...
