We stayed on the Executive level in August for a week. First of all, we found all of the rooms to be very nice...on the level of a Disney deluxe property. The privileges for the Executive level give you access to the Executive Lounge each day. Very nice Continental Breakfast served each morning (I believe from 6am to 10am). There are soft drinks available all day in the lounge area along with a few snacks (fruit, etc). In the evening, there are hot appetizers available, too. You could make a meal out of this if you wanted. I believe the lounge is open until 10pm or so each evening.
There is also a Concierge on duty for these floors at all times. They can help with any special needs. I believe the rooms have some amenity upgrades, but we did not see the standard rooms so I can't be certain. We found the rooms to be quite nice - real 4-star/4 diamond quality.
Have a great trip!
