Though I’m not a Diamond but a mere Gold, I thought I would try to register and see what would happen. I was given the following offer:
“You’re now registered to take advantage of this exclusive offer. Each stay through April 30, 2015, will count double toward the number of stays needed to achieve your 2016 tier status. Book now and get a boost on upgrading your tier status today. “
As with all of these targeted offers, it’s always YMMV but take a few seconds to see if you qualified for some free Hilton points or a 2016 tier status.
