Knowing that we were due to land in Dublin about 4:30 a.m., which was equal to 12:30 p.m. from my original location, I booked the room for the night before so that we could just quickly check-in and go to sleep. Instead, when we arrived at the hotel, there was no room ready for us and we had a long wait on the sofas. While the night manager comped us dinner (without alcoholic beverages), I did not think the hotel honored our reservation for the night. Someone gave our room - a double and a single bed - to a couple.
Dinner in their main dining room was an incredibly slow experience - ice cream on a desert was served without a spoon - and it took 10 minutes to get the spoon!
When I asked questions at reception, I got different answers - can you exchange 100 USD for Euros - NO, then Yes when another person overheard.
