Ireland or N. Ireland to Isle of Mann then back again - possible to do in 1 day? - hostels in northern ireland

Take a trip and want to visit Dublin and Ireland, Blarney, plus the Isle of Man and Belfast and Giant's Causeway in Northern Ireland. Due to time constraints, I would like to avoid to stay on the Isle of Man, but I would like to visit in any case. How can the next trip in June at the earliest possible? In the case of accommodation in the IOM is absolutely inevitable, we can recommend a cheap hotel, I can walk to the ferry in Douglas? There is no refuge in the IOM, is not it?
