Look at the Financial Statements of Pinnacle Entertainment (owner of Belterra) and you will see why comps are so hard to get. This once high-flying casino owner is on the edge of going under.
Go up the river a little ways, and play at The Grand Victoria casino. No where near as nice, but comps are good.
Don't stay at the casino, a block or two away, in the town of Rising Sun, is a hotel called "The Courtyard". EXCELLENT FOOD, EXCELLENT ENTERTAINMENT, and very nice suites (living room, kitchen, bedroom) that are cheaper than the casino hotel rooms.
