I've always wanted to go to Mexico. If you end up going, post pictures to Steemit, I would love to see what it's like there!
Big cities like Chicago seem so busy and overwhelming. London is a big city, but most buildings are low-rise and town-like. You don't feel rushed all the time.
Swimming is my hobby, nice to meet someone who saves those who can't swim! Sounds like a great summer job, too, being a lifeguard. :)
Enjoy your day!
