I searched the forum, didn't find anything relevant to buying points, thought someone here might have the scoop...

Situation: I have a long stay in DC that's upcoming, but I'm short a few HHonors points to cover the whole trip.

It looks like I can purchase HH points, $400 bucks for 40k points. I guess it makes sense to just buy the maximum all at once.

Before I plunk down the AMEX, are there any secret-squirrel deals or things to know on buying points that I might be missing?

Also, anyone know are these *BASE* points, or *BONUS* points I'd be buying? Doesn't say anywhere on the website,and I'd hate to not have them count towards Diamond...


Thanks...
