Honestly. Got the 11pm bus Cork to Dublin. It was packed as so few buses on late. Absolutely roasting. Had to ask bus driver to put on air conditioning. I didn't know if there was a radiator on in bus or was my seat over engine but the metal panelling next to my seat was boiling. Burned my ankle against it. Bus driver never announced we were on bachelors key so I had to ask him to let me out after he'd come back on his once I'd gathered my bags. Driver made no reply just heavy sighing. Loads of people drinking cans on bus, most people going out from airport If you can avoid aircoach, please do. Not a pleasant experience 2 stars are for driver getting us there. I imagine being a driver on that bus is no fun and he definitely seemed stresed/unhappy
