We ended up getting a hotel in Dublin this morning, another 4 star for $85. We then went to the regular site for that hotel and tried booking the same nights just to see, and it was $252 per night! So that was a really good deal. Unfortunately it was about the furthest away from what we were hoping for (the outskirts of the area we chose!) but I think it's probably worth it. The hostel we had planned to stay in was going to be $110 per night for a private room with shared bathrooms. Yup, I'd rather be at a 4 star hotel
