We want to travel by train from Dublin Connolly to Belfast (Grand Central, I assume, since only Belfast is listed). We'll want either the 11:50am or 12:50pm train but are willing to pay full fare flex, so that we can decide that day. Can someone confirm these trains don't sell out? I've searched several days starting as soon as tomorrow, just to get an idea and it looks like only the low and semi-flex tickets seem to sell out. Is that correct? Would we have any problem getting a ticket at the station, day of?
Our timing isn't too critical and we'd like to do something in the morning in Dublin, before leaving so that's why I want to stay flexible.
Thank you.
