From the POV of the guest, I'm not seeing a downside. The only changes seem to be that the mugs will be other than being able to get refills at any resort and if you are just staying for a few days, you don't have to pay as much. I don't know how many mugs we've bought in the past where we either were only staying for a few days or we only used it for the first few days and then just left it in the room.
