When most people travel, they spend some time booking hotel rooms. However, my friend Ashley and I were not like most people many years ago. We decided that backpacking through Ireland would be more fun if we “winged it”.

    Winging it, of course, meant that we’d each buy a one-way ticket to Dublin, and give ourselves ten days to get back to Bath, England, where we were enrolled in a study-abroad program. The plan was to visit Dublin, Galway, Cong, and finally end things in Belfast, where we figured we could catch a flight back to England.

    Unfortunately, Ireland had other plans for us, as nothing worked out the way in which we thought it would. After getting stuck in Galway and Cong for about seven days, we finally managed to take a bus trip from Cong to Belfast. The twelve-hour bus ride started at ten in the morning, which meant that we’d arrive in the heart of Belfast at around ten at night. Of course, like all transport, the bus ran late, and we ended up in Belfast at around eleven-thirty at night. As there were a ton of hotels around the area where it dropped us off, we weren’t too worried about finding a hotel room. But hotel after hotel turned us down.

    After the third hotel turned us down and the fourth one was locked up for the night, Ashley and I started to realize that we had to spend a long night sleeping on a city bench. Like militant soldiers, we slept in turn as we were worried we would get robbed. The system worked, as we were able to stay safe while catching as much sleep as we could on the bench.

From this experience, I really learnt a good lesson.
