Two river stops, then choose the rest
I am keeping Rike Park and the Bridge of Peace as the core Tbilisi plan. The market is the optional continuation in my version; Giorgi's version explores the viewpoint choice. Comparing them makes the next decision clearer. It also avoids a single crowded route that quietly assumes everyone wants the longest possible day.

The common start helps. I would compare the two extensions before choosing how much more to add.
Yes, and stopping at the river is still a valid plan. Optional should actually mean optional.
