Before I draft the full day plan I need three quick clarifications so the itinerary is accurate and realistic: (1) please confirm the exact pickup spot for your aunt (you said '7 km' from Thanjavur new bus stand — is that a village or landmark?), (2) confirm the location of your uncle in Thirivaiyaru (any landmark), and (3) what do you mean by 'Tamil Nadu Taj Mahal' — do you mean a specific local monument (give the town or link) or the replica often referred to locally (I can suggest the best match if you don’t know)? Also tell me your preferred start time and whether you have a private 9‑seater vehicle/driver.
