I called today to ask if I could buy one for our September trip, and they said sure we'll put you on the exception list. (I explained we were DVC members who usually get AP's but were planning on WDW next year instead, so only wanted 8 consecutive days)
If I had bought today I was quoted $221 for an 8-day. However, they couldn't charge my card today since they're supposed to sell me a 6-day with a 2-day upgrade to whatever the 8-day hopper price will be at that time ... since ticket prices are going up approximately $40-$50 it would be in the ballpark of $260-$270 and at that price I said I'll take an AP with my DVC discount for $309 instead at today's price since the Deluxe AP will be going up to $379 tomorrow, $359 with the DVC discount.
Hope that gives you some idea of what you would have paid if you walked up to the booth today/walk up to the booth tomorrow for an 8 day. But do call in advance and explain to them why you want an 8 day and not an AP, etc, in order for them to grant you an exception because they don't like to sell them apparently ...
