I've got tickets to Hyde Park and my partner said the same thing about me putting a damper on the show. I wish I could see her in Paris instead as it's more intimate (or ideally just go to both)
Train tickets down to London cost the same as flights to Europe, the hotels are the same, and the concert tickets are probably cheaper so it really wouldn't have been much different. My partner needs a Schengen visa to travel to Europe, there's noooooo way he's getting it on that short notice, and I don't want to go to Paris on my own honestly so I'm sulking
