Ok, this is a little weird, but since WL has VWL attached to it, there are more grocery items in the WL gift shop. You may want to consider wegoshop or another or the web based grocery delivery places. Disney also has direct grocery delivery, but do not know how available it may be for non-DVC resorts.
That's a fantastic idea! DVC's always have a pretty good grocery selection. You can combine the trip with a meal at Whispering Canyon or Artist's Point and enjoy the boat ride, too.
OK, here are some photos of the construction Triplefigs saw:

The new plantings are more tropical than the ones typically planted at the CR. The palm trees and larger plants still have the fronds bound together.
Traffic to the main entrance is being re-routed by a right turn immediately after passing the guard house then turning left onto the plaza (where the white trucks are in the third photo).
