Like many others, I have stayed at Marriott "one or two nights a year" ;-) and get pkgs all of the time. Several GMs have told me that official Marriott policy is: no charge to to receive or hold packages that are NOT for conventions or meetings (so long as they're of manageable size, etc.) but that hotels can, at their discretion, charge for convention or meeting related items. Out of curioisity, I asked one GM how they determine the difference between personal and meeting items, and he said it was based on where the pkg was delivered or picked up: delivery to a guest room or pickup at the bell stand or front desk is considered personal, anything else is considered to be for a meeting.
