Honeymoon in Dublin

Hey guys! So we’re going to Dublin, Ireland for 2 days. It is the closest thing to our honeymoon. I was wondering if you have any recommendations for us. Also do hotels actually like/accommodate if you write in the booking that you are on your honeymoon? Like is that going to make it any special or is it just embarrassing? Should we go for a really nice hotel for our honeymoon or does it even matter? Also is there anything romantic you would recommend in Dublin? Thank you guys!
