Andaz West Hollywood appears to be placing a 3-night minimum stay requirement on their entry level room types throughout the year.
What seems odd at first glance, until you dig deeper, is that they are imposing these 3 night minimum restrictions on both revenue bookings (paid reservations) and award bookings (free night awards) for the 1 King Bed and 2 Queen room types. And they are not doing this for the rest of their rooms.
