When renewing Disneyland annual pass can it be used on blockout date, or can I purchase a second annual pass?

My family has annual passes to Disneyland that expire in a couple of weeks. We want to go on a block out date becuase other family members will be in town . We know we can purchase block out tickets for $40, but we also know you can use an annual pass on it's first use even if it is a block out day. If we renew, can we use it on a block out day? If so, how is the best way to do this.
If we can't, is there anything that would prevent us from just purchasing a new, second, annual pass and using it for entrance to the park on that day. We would just throw the old ones away a couple of weeks early.
Is there any other way to accomplish this, or should we just pay the $40 block out fee?
Thanks

you CANT renew and expect to go in that day bc you did so when its blocked out. The only time you can do that is when its a brand new pass or has already expired. They wont let you buy a second one under the same name, its stupid. Pay the 40 bucks.

Go to the Disney Website...........they can answer your questions better. They also have a annual pass with no black-out dates.
