Okay, I just did a quick check using the Disney website and this is what I found based on the overall vacation dates you gave me:
I moved them around a little bit and checked on a day by day basis:
11/29 - GF main building concierge available
11/30 - GF main building concierge available
12/1 - GF main building concierge available
12/2 - GF concierge unavailable (either book another room here or move to the Epcot resorts area)
12/3 - BC/YC water view rooms available for $395 per night rack rate
12/4 - BC/YC water view rooms available for $395 per night rack rate
12/5 - BC/YC water view rooms available for $395 per night rack rate
You'll notice that I also looked at Epcot resorts as an option. I wasn't sure if you were picking 2 monorail resorts because you were planning on spending 100% of your time at the MK. If you have an interest in going to Epcot and MGM, I highly recommend considering an Epcot resort. The BC and YC are literally a 5 minute walk to the back entrance of Epcot and to the boat launch that will bring you to either park in 10 minutes. Plus at the BC/YC you have that big added bonus of Storm Along Bay. Every child's dream pool. The area is so different from the MK resorts. It's very lively and lots of fun. They even offer their own version of the GF Pirate cruise, it's called the Albatrose Treasure Hunt.
The reason why I moved the resort dates around a little bit, was to get you a reservation in concierge ASAP. My guess is that even with Merrie and you calling each week, the GF is not going to have anything open up until closer to when you actually go. I'd hate to see you lose out on one of the best features (IMO) of concierge and that's the pre-planning assistance. The sooner you can get on board with a staff member in that department, the sooner they can get going on your requests and any special needs. Even if you are splitting your stay between concierge and non-concierge, they will typically extend their pre-planning services to cover your entire vacation, as a courtesy.
And if you are still with me, I used a room budget of $3900 for the trip. That was based on the rack rates that I had shown for your original dates of 11/29-12/2 at the CR Tower ($385 x 3 nights) and 12/2-12/6 at the GF main building ($675 x 4 nights). If you were interested in moving some dates around and spreading out more, you can do 11/29-12/2 at GF main building ($675 x 3 nights) and 12/2-12/6 at the BC concierge level ($485 x 4 nights) and be within $100 of that original $3900 budget amount.
