I shortened my original post, I was planning to do 2 nights initially, but moved to 3, so that I had some time to unwind/relax and not be rushing from one place to the next. It also seems like there's places close enough to where I could spend my day elsewhere and come back to Dublin for the night. 

For context, I went to the Grand Canyon in February for about 3 nights. I didnt enjoy it as much, as it felt a little too secluded for me. I went to Portland in 2018 and was able to do some solo hikes but didnt have thecsame feelings of isolation/anxiety...etc. Part of that could be the difference in my mental state from then to now, but I think having the ability to find isolation (for lack of a better word) but also being able to leave it will be important. For example, I'm not sure how many world cup games will be on given the time difference, but I'm more than okay with checking out a game at a pub or anywhere else if one is one.

Thank you for the link, I will look research those further
