I don't spend much time in hotels (here's a breakdown of where I'm sleeping as I travel 365 days this year), but I've been looking at booking some upcoming hotel stays. I carry several co-branded credit cards, but as I've crunched the numbers, my Citi Prestige® Card has come out as a better option for paying the hotel stay in almost all cases.

That's especially true if I'm looking at a four night hotel stay, since the Citi Prestige® Card offers the fourth night free on paid hotel stays, which is an ~25% rebate (more if you're doing it right.

Update 7/9/15: All these deals are dead. The Citi® Hilton HHonors™ Visa Signature® Card has come out with an even better offer! 75,000 bonus points after spending $2k in the first three months.

Today (June 30) the 60k and 50k Delta credit card offers expire, the 50k Hilton credit card offer expires, and the ability to buy IHG points for 0.575 cents ends. It's a big day for procrastinators.

I do not know the exact times the credit card offers end.
