I Obsessed over 1 Prime Lens for Travel?

Just one prime lens for travel sounds good in theory, what if you don’t know what to shoot or where you’re going? I forced myself to use a different focal length everyday, 5 primes for a 6-day trip, but which lens do I pick when I’m tired, a little homesick? I headed back to Taiwan, my hometown - but I haven’t been back for 15 years? Getting lost on the streets with the OM3 and my other new camera will be how I get reacquainted with it.
