Get a bunch of cards and use this to hit the spending threshold. 30 Hilton rooms should take you pretty far. (For example, the CSP will get you 54,000 points after $4k. At 1.5 cpp (a low valuation), that's $810, over 20% back. The equivalent spending on the Hilton Surpass will get 5%-6%. Even asumming a 60,000 sign up bonus, thats 108000, which is between $450 and $540, an inferior rate.) You also may be better off crediting the Hilton points from the stay to an airline instead.
