This is obviously hypothetical at the moment but with our holiday of a lifetime cancelled in May and not likely to happen until next year now we are looking at the possibility of Dublin or Barcelona for 3/4 nights most likely at the start of October. We would only be booking a fully refundable hotel now and probably leave booking flights until at least the end of August to see what the situation is in both cities (this could end up being our deciding factor anyway).
I've never been to either but DP has been to Barcelona a couple of times for work, he's never done any of the touristy bits or had free time to spend there though. We are both mid 20's and no kids.
So coronavirus aside, out of the two which would prefer to go to? I know Dublin is very expensive once you are there (seen a few good deals on hotels though) but I'm assuming Barcelona will be quite expensive too? We can afford hotel/flights for either so it might come down to where we will have to take the least spending money, our holiday in May was fully paid for so we hadn't budgeted for another trip this year!
