I don't think you do get a discount at non club resorts, nor do I think you can make this reservation thru member services. You are going to have a great time at the BWV's. We stayed there 2x and it is great - so convenient to EPCOT & MGM. Be sure to check out the Bellevue Room & Jelly Rolls. It's also a nice walk over to the Swan & Dolphin.
BTW - how do you do that cool count down thing? We are 45 days away and are VERY excited!
