Changes

There is are ferries from [[Wales]] ([[Holyhead]] in the North and [[Fishguard]] in the South), from Scotland (Troon, Cairnryan, Stranraer) and from England (around Liverpool). Currently, it might only be possible to get across without paying if you can find a sympathetic driver who allows you to hide in their vehicle, as every passenger pays separately. From Birkenhead there is a ferry with DFDS seaways that goes either directly to Dublin or Belfast. Two ferries per day, one in the morning and one in the evening. If you can find a driver who has already paid for his car + 1, then it is possible to amend that ticket and check in with the driver for only 10 euros. It would still be paying, but on the ferry you get a dinner buffet and breakfast buffet.  Your driver will also get a cabin with his ticket with four bunkbeds in it, so you will depending on wether your driver wants you in the cabin or not, get a night on real sheets. (Cheapest alternative I have been able to come across if you are still to do it in any legal way.)
