If you are looking for a hotel to stay in during the 2016 Formula 1 Singapore Grand Prix (16-19 September 2016) this year, check out the Conrad Centennial Singapore because reward nights are wide open for redemption! While I usually do not advocate burning your Hilton HHonors Points in Singapore since that 60,000 points can be put to greater use, it is actually wise to use them for the F1 period if you intend on being here.
The cheapest rate I can find for the Conrad Centennial Singapore is S$873++ under the HHonors Discount rate - this comes up to approximately S$1,028 after taxes. Redeeming 60,000 HHonors points would value 1,000 points at approximately S$17 which to me is pretty great value since you usually only get around S$5 on regular redemption during the weekends.
If you do not have enough Hilton HHonors points, you should definitely consider buying them if you have the intention of redeeming for room nights at the Conrad Centennial Singapore during the F1 period this year since you would most likely be targeted for a bonus - my personal account gets a 80% bonus. If you were to use your points to book the room instead of paying for it, you will only spend US$340 (approximately S$463) instead of S$1,028 (55% less!) for a night at the Conrad Centennial Singapore.
