I need 3 people to stay for half day what is the price
For Half a day, please give a call directly to the hotel & ask because all sites give rates for at least one day stay.
check online travel sites they sometimes give better rates like makymytrip etc and secondly Chennai has a 24 hr check in check out system so it doesn' it matter how many hours within those 24 hrs u spend there
Check online portals for better rates
I stay as a couple for 2 days and got a rate of about 4900/- + tax. All I can help you with is that even if you call up hotel, they give you a rate thats higher than online rate. Its better for you to book online before you get to the hotel. Choose any website to book, most prices are in ballpark.
