I've stayed at multiple Four Seasons, various other 5 and 4 stars, and probably 10 deluxe cash stays at WDW. I've never seen laundry outside of rooms, at any time of day from other guests. Room service trays of course, while some consider tacky, is common because it doesn't have a home in the room. If a very fancy hotel, it's brought on it's own table, call down and they retrieve the table and plates. Bath towels go on pile on the bath room floor or in hamper for the housekeeper and new towels are replaced.Meh, this is common at much nicer hotels than this. As is putting the room service in the hall.
The difference is the Disney housekeeping, who I guess just rolled on by.
