I have been watching the AP GCH prices and noticed the prices change up and down every few days. Also I have found the the view rooms are only a few dollars more on a 5 day stay.
Example for our trip
Arrive 12/7 leave 12/12 (5 nights)
GCH standard view price: $1604.25
GCH view room price: 1696.25 << This is what I have booked
(Prices include 15% tax)
Per day difference: $18.40
My recommendation is that once you book your AP rate, continue to watch the AP prices on the Disneyland website. I have seen them change as must as $80 per night.
Also, there is no current refernce to the AP7 rate discounts.
