laundry service package on constellation

do they offer a laundry package on the constellation?

No laundry package. Laundry & dry cleaning is charged on a per item basis. Sometimes the ship will offer a laundry special- it is a stuff the bag. All you can stuff in a paper laundry bag will be washed and folder ( not pressed) for $50.

I would not recommend putting anything delicate or that could shrink or fade in the wash & fold bag.

thanks for the info.
