Mate you can stay in Geshame Hotel, Really nice hotel if you are not on low budget. You can get your hotel booking done from dublinhotels.ebookireland.com or goireland.com Otherwise you can try self catering or budget hotels For travel advice simply check tripadvisor.com.
I have personally used The Westin Dublin multiple times I have used their hotel multiple times, their service is top notch. As an american traveling abroad its comforting to stay with a recognizable brand name. Additional they have Good ratings on HotelTattler.com and Trip Advisor.
The Arlington Hotel comes very high rated. Not sure what you're willing to spend. I like the site qype.co.uk for ratings and travel advice.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
