Of course, it's Winter Wonderland in Hyde Park.
C and I has such a fun girly evening out, with mulled wine, cinnamon sugar churros and a couple of exciting rides. I was thoroughly reminded of that unique adrenaline kick you get from scary rides - you see that tower there? Yep, we went on that, the one where you get dropped down at an alarming speed. It was exhilarating, but I can't lie, pretty terrifying!
I would advise Londoners to go on a weeknight if you can, because I know it gets crazy on weekends and they sometimes have to shut it due to overcrowding. It's definitely worth a trip though, and don't miss the churros!
