OK, so we need to make a decision by Monday, so we can get tickets (for those of us who are sure they are going).
For me, ideally I'd like to fly in to wherever Friday and leave Sunday or Monday. I'm not worried about wrangling the time off, that's not usually too hard. So let's make a decision on three things - visit location, visit duration, sleeping arrangements (ie, do we all want to fend on our own, do we all want to rent an air bnb together, do we want to look at hotels. Some people may have their own places to stay or whatever, and that's fine too.
So for me, I am saying, Friday-Sunday, Dublin (5/5) London (3/5), rent an airbnb seems cheapest.
