I extended my Ambassador membership 2 days ago for 200$ + getting 25k points bonus as a special offer, and yes, its the second consecutive year i am doing this while not meeting the Spire requirements, yet the Spire has been extended right away, and this time its even extended untill enx of 2020
I would advise you to choose the money option, and maybe you can even get 25k in addition to the free night certificate, which is definitely an excellent bargain ... good luck dude!
