I will be in Georgia next month for 1 week. I am staying in Tbilisi the whole time and already have things planned but am looking at doing 1 more day trip, most likely to Sighnaghi. However, is it feasible to do Sighnaghi and Davit Gareja in 1 day from Tbilisi, or is this too much? I wont be driving but would be looking at arranging a private tour. I will also be travelling with a young child, which is why originally we were thinking of just going to Sighnaghi as it's easier.
