Please do not take offence but I would have varied the hotels I stayed in for a trip like this. Surrounded by rich Americans cocooned in contrived luxury is fine for a day or two but I would get very bored/frustrated quickly.
There are so many great smaller hotels/guest houses available where you will get to meet all kinds of travellers and 'normal' people.
(I say this as an Irish resident and one who worked in Dromoland Castle some time ago. Its all a bit of an act from the castle and decorations to how the employees act).
