Only a handful (30, according to Buzz2001's CSR website), so they book up very quickly and unlike the value level family suites the CSR suites have historically been excluded from all discount codes. That makes them very undesirable for us, because we'd have to pay the full $350/night rack rate plus the full price for our dining package even though we've always traveled at times when we'd either get a room discount or
free dining if we chose any other accommodations.
