I received Amtrak offers regarding Rocketmiles. Basically, if I book a hotel through Rocketmiles the first time, I get 3000 Amtrak points. The value of the points varies somewhat according to route and date, but the 3000 seem to be worth around $50, so that would make taking a $20 hit on the hotel not a bad thing.

It's a tribute to CET that they couldn't manage a similar promotion (yes, Sheldon, that was sarcasm).
