Where to stay in Dublin

I'm (30F) will be in Dublin for a few days in June. I'm going to a concert at Marlay Park on Sunday and then flying out the next morning at 9:30. My plan is to take a Marathon bus to and from the concert since that seems like the easiest option. I think the concert ends around 10:30 and I'm assuming I won't get back to Dublin until closer to midnight.

On Monday morning, I was planning to get a Dublin Express to the airport around 6:30.

I am a bit torn on where exactly to stay, mostly in regards to safety in walking back.

Option 1 - stay on the edge of Temple Bar, closer to Trinity. This would be a longer walk from the Marathon bus stop (about 20 minutes). However, it looks like I'll be close to Dublin Express stops for my early morning bus ride.

Option 2 - stay closer to the Marathon bus stop, likely on the other side of St. Stephens Green which seems to be about a ten minute walk. That would mean a longer walk in the morning to catch the Dublin Express bus (about ten minutes which would be with luggage).

Which should I go for? I think I'd rather do Option 1 to lessen my time walking around with luggage the next morning. I just worry about the safety of walking alone back up to Temple Bar that late.
