I'd say wait until you see the next round of promos and go where you get the most free nights/points. SPG is doing every 3 stays = 1 free night at a resort until the end of July. It's not quite FFN, but it's decent.

I've qualified for SPG Plat, Marriott Gold, so I'm going to try and focus on Hyatts now, but they are just not always where I need them annoyingly.
