If it only dips down to 28 for a few hours, you should be ok if you can drain the water lines. Just open the low-point drains and open all the faucets. If it's not below freezing long, the P traps should be ok.
Leave the heat set to it's lowest setting and keep the doors under the sinks open to ciculate warm air if you are really concerned.
