I know I should know this, but all these rules confuse me sometimes.

If I buy a return from Dublin to Sligo, can I break my journey for an hour or so at Maynooth?
Does it make a difference if it's a web fare special rate?

If I can't break my journey, can I just buy the web fare ticket for use from Maynooth onward, and a single from Connolly to Maynooth? (since you can't book online from Maynooth) Presumably doing this means my seat reservation is no longer guaranteed?

Sorry for all the questions!
