This is the normal arrival gift for a FS Marriott. For the non-FS hotels, you would get 200 points (250 for non-NA CYs) or an item option. If the hotel has a little mini-mart close to the front desk, I'm usually offered the option of one or two items from the mart. If they don't have the mini-mart, then they will normally have a small bag with a couple of bottles of water and a very small bag of cookies.
