If you could go back a few weeks, what would you tell your old self to better prepare for the trip? What specifically would you do differently, and why?

If I could go back a few weeks and prepare better for this trip there’s a lot of things I would put into consideration, starting with the style of clothes that I packed for this trip. I started planning for London with the hope of it being very warm most of the days even though I knew London isn’t known for being very hot and has spurts of random rain but I was blinded by the summer vibe and bought a ridiculous amount of shorts that won’t get to be worn till I am back home. I actually only got to wear shorts one of the days that I was here and it ended up raining. Luckily I overpacked and had enough pants to get me through. Another thing I would have told my old self to better prepare for was to convert my US dollars to pounds weeks before I left because I tried to do it on the last day and ended up having to swipe my hard the whole time which made my cash useless.
