> 80k offer from chase for their IHG mastercard which expires mid February, each 1k min spend

register to IHG site, you can sometimes get 80k+$50 credit offer. Also, through April you can book some IHG rooms in certain hotels for as low as 5k.

> SPG Amex - I never really got into SPG and 3k spend is pretty steep for only 25k points, regardless of their versatility. However I imagine this card is going away after the merger so soon rather than later might be better.

If your Serve is still active, then just serve it! But yes I would get it within next 3-4 months.

> Citi Prestige - the 4th night free benefit would be quite useful since most of my stays are paid at the moment as I build my point balances.

get $350 AF offer in branch.

> Citi Premier - Supposedly their are card changes coming up later this week. I just received a targeted offer last week for the 50k bonus which is valid until mid march.

maybe sit this one out till march then?
