I said this when they were on their last holiday, but it still stands. They act like two girls who have met on holiday and their parents are letting them run around during the day together, they’re playing dress up (swear to god if they say “this looks so Parisian!” one more time), going shopping, eating at well known places, seeing one sight, and then running back to the hotel room before curfew.
You can tell these two girls think they’re very mature and independent, I’d argue that the way they act actually shows that they’re very sheltered, naive, and immature for their age.
