The first day I would build
Give the city one clear route before adding extras.
- Start with Old Town and Toompea while energy is high.
- Use Telliskivi as the natural reset instead of crossing town too early.
the easier plan is Old Town and Toompea first, Telliskivi or Kadriorg afterward. That keeps the day readable instead of turning every good name into a separate detour.
I would rather leave one place for tomorrow than drag a tired route through Kadriorg just because it looked close on a map.
