Concierge is located on seventh floor rather small floor -- w/secured access (insert key in elevator slot to get to 7th floor). Concierge food area overlooks WL lobby. Tables are available. Concierge food area not far from any room.
Concierge rooms are same size as rooms in rest of WL. Three views are available: Magic Kingdom, inner courtyard (pool/waterfall), and overlooking WL villas.

There's also a review of WL concierge by someone who's stayed there at

I don't know anything about chances for upgrades in June, though!

Good luck!
