what do you think about going to the roller skating disco in.
It's a 5 minute walk from the Kylemore red luas stop. Also buses 18, 151, 13, 68, 69.
Price is 15 euro which includes skate hire, they have the regular roller skates (not blades) which are easier for newbies. You can also get wristbands / protection if you're really thin (they have kids sizes only). Good idea to wear thick socks or bring insoles as skates can hurt your feet otherwise.
There's nice music. Most of their customers are children, apparently made out of rubber if you pay close attention to how they skate + roll over.
If you haven't skated recently it's a good idea to skate 1-1.5h max for the first time. There's a refreshments area for drinks / chat.
If you can't find the place call me / text me at 0834029944.
