No problem!
In fact, this is the sign of a real backpacker. Most of our guests are "off the beaten path travelers" and don't make their travel plans far in advance. You only need to make a reservation for your first day of your arrival.
Once you are here and can check us out, you can pay for those additional nights when you check in. Whether you book direct with us (preferred) or book with a third party booking site, you only need to book the first night.
We can do this because we do not reserve every bed in the hostel so there is always room for guests that want to stay longer or for last minute walk ins
