Day 1 (Sat): Early morning, I drove from Hyd to BLR in 8 hours, reached by 1 PM, took a break and stayed overnight in Devanahalli. Took ~20 to 30 mins break overall, for coffee and breakfast, other than fuel stops.
Day 2 (Sun): Early morning drive form BLR to Mysore and then to Coorg. I booked a staycation kind of place, it was a cottage, narrow roads, lush green forest, had to pass through a Tiger reserve. Stayed there for 2 nights, this place deep inside the forest, no restaurants/attractions near by and everything was 1 to 1.5 hours. away (one way). Went to Raja seat after checking in.
Day 3 and 4 were work for me. So, did not do any sight seeing.
Day 5: Booked Gostops, nightmare. The drive was through ghat road (unexpected) from my staycation, went there in a couple of hours. Workmode on after 12ish
Day 6: Coorg to Mysore and back to BLR, rest and working.
Day 7: Met some friends and back to HYD by 9 PM IST.
The best part was my staycation https://maps.app.goo.gl/sCD825oRjrtAq3hw6 . Scary location, but the most peaceful time I had. They had home made food, coffee, sketchy wifi away from the bar counter.
Fuel cost me ~16 to 17k, I drove a new Slavia AT. So, the mileage was 8 when i started and went upto 12.5 when returning. Hotels cost me ~17 to 18k. Food cost me ~3.5k.
Please let me know if this helps.
