This is NOT just through travel agents, and Disney themselves have been calling people 14-21 days before arrival to notify them of a transfer. Apparently this is a rather sudden decision... and disney is scrambling.
When/if you recieved a call... Disney pushed for transfers to studios/1-bedrooms at SSR. If you were unhappy with that choice, they would also suggest the Beach Club, Boardwalk, and several other deluxe resorts, but not all. Ultimately, they would meet your resort quest if possible.
Apparently the construction noise, equipment, and activity is extremely noticable and too overwhelming when factoring in guests. I also heard that only floor 3 and 4 were open.
You are not the only AKL traveler to be moved, and it looks like you picked a great resort to move to! I've seen at least a dozen others be offered "transfers" regarding this same discussion.
From the DVC brochure I recieved, they're converting rooms a section at a time. Unfortunately it's at home... but I wouldn't be surprised if (at later date) they "transfer" those staying in standard and pool view rooms due to that section being converted.
