The bus was clean and the driver was good but it’s terrible that there are no toilets. The Dublin to Belfast route is 2 hours. The bus I was on was an unbranded one and actually did have a toilet but it was locked. Unfortunately I didn’t use the toilet before leaving the airport and pretty early in the journey realised I needed to go. I asked the driver for the key but he said it was out of order. I said I might need to get off and he said he wasn’t allowed to stop. I waited for an hour which was terrible and eventually put on my coat, grabbed my bag and demanded he let me off, whereupon he gave me the key and let me use the toilet. I am not annoyed at the driver, he was following protocol but it made for a very uncomfortable journey. I am someone with no health issue but people with weak bladders, pregnant women etc should avoid this service.
