This must have been asked many times here but I can't find the answer.

I'll be flying business to Dubai in a 777-300ER. I would love to get the window seat but I'll be flying alone. I tend to drink a lot and go to the restroom many times during flights (and especially in a long, overnight flight). How hard is it to go over a stranger's legs at 3am in the morning in our original time zone? Is it better to just take an aisle seat?

Edit: Tend to drink a lot liquids not alcohol lol
