Journey to Dublin was ok, the bus was nearly full so my partner and myself had to sit apart, no big deal but if we could’ve booked seats together we would’ve. The journey back to Cork…. Well, the driver seemed to be more eager to get to Cork than any of the passengers ( although we very nearly missed the turn off M7 for M8, so just avoided reroute to Limerick) We raced from Dublin airport to city centre travelling at speeds well above the limit overtaking and undertaking traffic including taxis, who as we know don’t be crawling. We arrived at city centre got all passengers onboard and then had to wait 7 minutes before departing as we were too early for the stop. On the motorway I noticed the bus was restricted to 100 so no speeding but lots of drifting into outer lane then over correcting into hard shoulder and vice versa. Approaching toll plazas at excessive speed as well as Dunkettle interchange, and arriving 15 minutes early. We would have much preferred to have had a comfortable journey where we didn’t feel in danger and arrive on time.
