Hilton: Donate $5 To Lyft’s Vaccine Access Program & Get 2,000 Points also possible free Lyft Ride and Delta Points
$5 for 50 URs, 250 Skymiles, and 2000 Hilton points is well worth it. Hilton points are generally worth .4-.5 cents each, but likely worth more than $5. Plus the donation will help people get vaccinated and a good way to keep points from expiring.
Cheapest redemption I saw in a quick search was 9k in Deadwood, SD.
