Jetsetter is having a flash sale for the
Hansar Bangkok starting at $99 a night for some dates. There are some blackout dates around Xmas and New Year but otherwise seems pretty open from now till then.
Members also got a coupon for $75 off good on bookings made by October 12th. Combined, that's a pretty attractive deal.
If you'd like a membership invite for Jetsetter, ping me and I'll send one your way.
