I agree with you about exploring cities on your own, @themadgoat, and it's the way @tim-beck and I would normally travel around a new place. However, since we had his daughter with us on only her second trip out of South Africa to date, we wanted to give her a crash course in Paris. The Paris Pass and Hop-On Hop-Off tour were a good way to do that. Getting lost and making wrong moves on public transport took care of the serendipity factor 🤣🤣
