yeiiii finally someone told the right think about parking,congratulations!!!!!
I let you know guys,in Santry,free parking=costa coffee and around(spar,home base,actually there is a huge car park) and yes every block has visitor spots,you text your registration number and get free parking for 24hours,actually you dont have to do it,just ask the lady that you are going to visit,and she will do for you,this in what im doing for my visitors to make them feel more comfortable and relexed.
For Sandyford,Dunnes is the best car park,2hrs free parking,or someone said something about the luas stop,there is a car park pay and display.After you park the car just contact the lady or send her a quick text that you have arrived in the area,she will direct you to a corner where she can see you and then she will easily text or call you for the last directions.Read with attention the text and follow all the directions relaxed...so easyyyy guysssss.
good luck xxx
