Ireland
The Enterprise train which runs between Dublin and Belfast has a number of first class carriages with huge, reclining seats at one end of the train for First Class ticket holders only.
However, 50% of the trains have a first class carriage which can be used by standard ticket holders at the opposite end.
Dublin is not a massive city so you can get to most places on foot. Phoenix Park is a bit of a trek but well worth it. A walk round Merrion Square is a lovely escape and several walks around the Temple Bar area are inevitable. So my tip is pack trainers!
