Yes, Silvers and non-elites can redeem points for awards at RCs.

Actually the points/night can be higher than even that (and quite a bit lower). Check out Partner Hotel Rewards . If you notice in the upper right-hand corner under "Related Links" there is a link to RC Pointsaver awards. Those can bring the points/night down to around 20K/night. And there are some nice RCs that participate. I've stayed at the Cayman Islands RC using a Pointsaver award and was very pleased with the stay and the award.
