So if there wasn't enough Hilton offers, there are incognito offers for the HHonors no fee and Ascend cards now. I couldn't pull it up but others have. And like any AmEx special offer like this, if you pull it up, don't let it go; you might not get it again. So maybe don't look until you're ready?
No fee: 100k for 1k spend, link and tips here -

That no fee is kinda tempting (which is why I admittedly tried a couple times casually when it was posted, hehe). I haven't put much thought into it, but I heard Hilton is easy to transfer points to pool them, is that so? I don't have a need for Hilton points just yet but if they keep upping the offers it might become compelling and ideally I'd like to just pool them into hubby's existing account eventually.
