Each trip we call our host to set up the Limo ride from the airport and room. When we ask about Free Play he asks if we have any offers and if so we have to provide the code. I thought just like the rooms, the host is able to arrange some Free Play as well. He never asks about codes when providing the room so why do so with Free Play? What is the official word on this? Are hosts allowed to give out Free Play or only allowed to give out what is currently assigned?
