I"ve been looking at what information I do have and it may be a bit late for a full Travel Tips post but I"ll see if I have time for something later on.
Here"s a hotel list from APAT partner, LateRooms although you may be able to find bargains / discounts by
Booking elsewhere.
LateRoomsEDIT: I had hoped that the LateRooms linked map would remember the search & distance parameters but apparently not. Please see the GMap lined below to refine the area for the LR search.
Prices are not cheap at the moment but the value of the bunch is the
Leeson Inn Downtown for around £70 per night (Assuming 3 nights) which is a 10 minute walk from the Fitzwilliam Card Club which is at:
Clifton Hall
Lower Fitzwilliam Street
Dublin 2
Google MapCasino is 20 to 25 minutes from the airport by cab.
If you need anything else, please ask.
