Route Taken Chennai Adyar to Trichy -
via Tiruporur-CGL-NH 45 - Tiruporur-Chenglepet road is almost complete with the expansion work. Improved a lot compared to my earlier drive during Oct. On Nh45, few places, there are diversions due to flyover construction or road repairs.
Time: ~5 hrs Trichy - Thiruvaiyaru -
Via Kallanai - Good and winding State Highway. Less traffic in the afternoon. The only hurdle is crossing Kallanai.
Time: ~1hr 15m Thiruvaiyaru - Tanjore - Expanded and beautiful highway, heavy traffic segment. Tanjore Bypass is well constructed and beautiful.
Time: ~45m Tanjore - Kumbakonam -
via Thittai - Village Roads but much much better than regular NH connecting the towns. However, a new 4/6 lane Greenfield highway is getting ready. Flyover construction is seen near Pateeswaram.
Kumbakonam - Chenglepet -
via Jayamkondam, Veppur, NH45 - Traffic is bad till Jayamkondam with lots of slow-moving trucks/tractors carrying the farm products. Vridachalam to Veppur road is full of patchwork and not so great. I was skeptical about going direct to Ulundurpet from Vridachallam as not very sure of the road condition.
Time: ~4hr Chenglepet to Adyar -
via Mahabs, ECR -
Suggested by Teambhp member - narayans80 - Though the distance is a little extra, I would say this is the only passthrough in Chennai where you can keep moving even during peak hours. CGL to Thirukazhukundram has an expanded 2 lane SH. Thirukazhu - Mahabs is also 2L regular SH. Took me 1.5 hrs to reach home. This is better than Chenglepet - Tiruporur - ECR.
Time: ~1hr 30m Stay and my experience Trichy - Hotel King Paradise - Recommended for Family. Located on NH45, it has a very good parking space and a good budget hotel for the facilities provided. A very peaceful location unlike the interior of Trichy/Srirangam. If you travel by car, this is a good place to stay. However, we did not use the restaurant. The downside is the room service is a bit late as there is a lack of staff, but very courteous.
Tanjore - Hotel Sumi Palace - Ok type of hotel for family. Located near New Bus Stand. The facilities are ok, but the room we stayed is a bit cramped. The downside are lack of good food joints nearby and the rooms are so close to each other that you can hear what the next room occupants speak. The reason we stayed here is we couldn't find any good hotels near Big Temple, due to last-minute booking.
Kumbakonam - Hotel Rayas - Worst of the services for the price they charge.

First-of, disconnected intercom facility in all rooms. For everything, we need to walk to the receptionist on the Ground Floor. Toilets are stinky and the flushes don't work. Poor beds and uncleaned covers. Moreover, they forced us to take an extra bed for the kid which was not mentioned earlier when we booked the room. Also, the extra bed is so-so dirty that it was only used by those bugs who spent the night along with us. Luckily, as we traveled a lot the whole day, our tiresome took over the fear and we just slept.
MY RECOMMENDATION: DONT EVER GO TO THIS HOTEL, I WOULD NOT. This is my experience and others may differ. When I checked out, I wrote all these in their feedback form, they casually replied - we will take care of and improve next time. It sounded like -
Who would ever care for your feedback? We will continue to loot.
Food Stops Day 0 - Friday Dinner: A2B Restaurant, Before Samayapuram Toll - High Quality Food. Restrooms are good.
Day 1 - Saturday:
BreakFast: Hotel Parthasarathy Vilas, Thiruvanaikaval - Best Authentic food and very tasty. It is a very old hotel and its specialty is Ghee Roast. Don't expect any great ambiance or good service. Just enjoy the food. Not an HI-FI Hotel. Must Visit.
Lunch/Dinner - Hotel Temple In, Srirangam - Good Hotel and fast service.
Day 2 - Sunday:
BreakFast: Hotel Lakshmi Nivas, Trichy near UchiPillaiyar Temple - Ok Hotel. Nothing special
Day 3 - Monday:
BreakFast: Hotel KrishnaBhavan, Tanjore near Big Temple - Good food and service
Lunch: Hotel Sree AriyaBhavan, Tanjore - Very good food. We took Dhivya Bhojan which is a complete meal. This is a 60 years old Hotel. 5 Star rating
Dinner: Hotel Padmavathi, Kumbakonam(Nr Hotel Rayas) - Ok Hotel. Nothing Special.
Day 4 - Tuesday:
Lunch: Hotel Udipi Ruchi Cafe, Ulundurpet - Great Ambience and you can park your vehicle under the shade, unlike the adjacent A2B. The food is very nice and the people are very friendly. Not much crowd. This is much like Hotel Sai Sangeet on the CHN-BLR-SLM Belt. I would prefer this over A2B.
Overall, it was a good trip and a very good lesson for me to plan next time if, at all, I am going to Trichy and Tanjore.
We were able to cover over 30 temples in just 3.5 days. How we made it? We followed one simple rule,
REACH YOU FIRST DESTINATION BY 5:30AM. We also ensured that we don't visit any place in haste and atleast spend half an hour in every temple.
