-2 Cat 1-7 certs (one at 60 night credits, one at 100)
-1 Cat 1-8 cert (at 150 night credits)

Based purely on spend, you'd need 145 night credits on top of the 5 you get for being a cardholder, so 73 sets of $5000 spend = $365,000. Probably not the way I would spend $365k on a credit card (particularly if the bulk of that spend accrued only 1x/$).
