3 Days in Dublin Ireland: The Perfect Dublin Itinerary
"For example, it doesn’t include attractions like the Dublin Zoo, Avia Stadium, the botanical gardens, the wax museum, or trips out to Dalkey or Malahide Castle. Be sure to check on admission days and hours for any must-see attractions before you set out as some attractions close for one day per week, or may be closed due to a special event or renovation. Many attractions have reduced winter hours and longer summer hours."
