There is currently an opportunity to earn 7,500 bonus Hilton Honors Points after two eligible stays consumed before 31 January 2020. Registration for this offer is necessary and members will receive credit for the stay challenge if any portion of the stay falls between the promotion period (regardless of check-in date).
While the terms and conditions of this offer does state that it is only "valid and exclusive to the recipient of the email invitation", I did not have any trouble signing-up for this offer. Members who register for this 7,500 bonus points offer will earn bonus Hilton Honors Points from the very first stay:
First Stay: 2,500 Bonus Points
Second Stay: 5,000 Bonus Points
If you have an American Express Card, this is a great way to double-dip on that Spend S$500, Get S$200 offer with Hilton - just make sure you stay at one of the participating properties! If you are thinking about getting the card and would like to pick up some additional miles along the way, using my unique referral link for The Platinum Card will give you 40,000 more Membership Rewards (MR) points (equivalent to at least 25,000 miles) on top of the welcome offer of 75,000 MR points (equivalent to at least 46,875 miles).
