I saw from Bangkok Renaissance Facebook page, they will have half price flash sale on Aug 2.
Booking Period: Aug 2 – Aug 4, 2016
Stay Period: Aug 2 – Sep 30, 2016
Bangkok Renaissance Hotel is located near BTS Chitlom. It is less than 2 minutes walks.
My Conclusion
Best available rate of Bangkok Renaissance hotel is now around THB 4,600. So half price will be around THB 2,300??? I also not sure now. Let see on Aug 2.
