I second it: get the Hilton Amex Aspire Card. You automatically get top Diamond status and the card benefits easily exceed the annual fee. Within a month of getting the card, I collected a $250 resort credit, a $100 stay credit and then a $150 Amex benefit for staying in Hawaii. And then there's also the $250 credit for airline fees.
With Hilton Diamond, you will get free breakfast just about anywhere you want to stay and lounge access wherever it's available. I have had a few sub-optimal stays at Hilton properties, but whenever I say something THEY ALWAYS MAKE IT RIGHT. They have heaped absurdly large numbers of points at me for small failings (e.g. no water bottles in the room).
