I sent an email to the site and was informed that the ROC site would be closed for 5 days, beginning May 16th and opening again on May 21st. I trust the Queen will enjoy her trip to Ireland. Like many tarvellers we spent months planning our first trip to Ireland, and also built in lots of time to be flexible. Being quite a history fan the ROC was very high on our list of things we couldn't miss. We allowed 2-3 nights minimum per location to deal with unexpected events. However, obviously not enough time to deal with a 5 day closure so one family can spend a few minutes on the site. I shudder to think about the poor toursist who planned a trip to Dublin during the Queens visit. One would assume the entire city will close. Anyway, this is a travel site so I'll hold off on expressing my opinion about this visit.
