Hotel Points Credit Cards
Hilton HHonors American Express - 50,000 sign up bonus
My wife and I both have this card and we've stayed at Hampton Inns and at an amazing resort on Marco Island, FL with it. You get 50,000 HHonors points after spending $750 in 3 months.
Note: Before you sign up for the cards, sign up for the Hilton HHonors program.
*Also be sure to read the terms and conditions.
