I just learned that if we take a guided tour that uses Marriott hotels, we cannot get our usual elite benefits till we arrive. At this point, rooms have been assigned so there will be no upgrade. We can give out rewards number which will allow CL access. The nights don't count towards out count. I have lifetime benefits so the nights being counted does not matter to me but might to others. They also do not count towards any promotion. We don't get rewards points either.
