Having called them early in the day to make reservations in Ireland, we needed 3 rooms. They could only make a maximum of 2 per reservation but assured us they could do it with 2 reservations. When we finally received the confirmation e-mails several hours later, the were several errors. After multiple calls to them, finally asking to speak to a supervisor, we were cut off each time.
We finally called American Express to cancel the charge-confirmations and will make our own reservations.
