Bus condition: Bus is new, and seats were large and excellent space it it is 2(L)x1(R), and same withthe sleepers(berths).Berths were larger for couples(2x) on the left and 1x on the right(side upper). Total of 25 seats only including berths(so excellent space).
Punctuality: while Chennai to tiruchendur starting(7:30pm) was delayed by 30 mins due to traffic delay at Chennai pickup points like perungalathur and vandalur, despite it reached tiruchendur on time(15 mins delay though)!
While returning I took the 8:30pm, and it reached Chennai promptly on time early morning by 6:45am(since no traffic delay outside Chennai).
Staff: staff did best and with courtesy the amount of pressure they were dealing with at boarding points.
Overall: Good for now :)
