Me and my wife are coming to Ireland in the end of May. We'll have 10 days for both: Dublin and a tour around Republic.
We've never been in Ireland before, but we've been dreaming about the visit for a long time, so our expectations are quite high

You can help us with answering various questions. Or just remove the thread if it's too inappropriate

1) I've roughly estimated price per double room at 60 EUR per night. Now, after checking through websites, it look like ~ 70EUR is the cheapest variant for places along the road (not in Dublin).
The questions are:
- is that right?
- if we speak about the end of May, is it possible to make reservations by phone 1-2 days in advance? Or should we book every accommodation in advance, let's say now.
2) We are going to post updates about the trip to twitter/facebook/google buzz or similar services. As I understand, we should not expect wi-fi in hotels for 60-70EUR, so we will need a prepaid SIM-card with data services enabled. Any suggestions?
