31 is my favourite row in Y. Even on a full plane I’ve not found too many people congregating there as there’s about 6’ or more of room. I just stretch out and close my eyes.
The wing seats are a bit more restricted due to the doors.
If you booked 31B you may well find a couple offers to switch

Even if not though I love being able to use the washroom without crawling around other people. And not getting disturbed myself. It’s basically like everyone has aisle access.
