What plans could a prospective cryonicist try out, beyond simply signing up, that could increase the odds of eventually having a pleasant re-animation experience?
If one has Alzheimer, then one could sign up to a cryonics organisation (if not done yet) and then go to the nearest hospital to this organisation, call the organisation to tell them they will die, call the hospital telling them where they will commit suicide, and then commit suicide (by minimizing the damages to his/her brain). This will stop the Alzheimer to deteriorate their memory further and therefore having a more pleasant re-animation experience.
Note that I am not saying this is necessarily the best thing to do because I don't know what are the chances that cryonics will work, I am just saying that it would probably be a more pleasant re-animation experience.
Basically you'd have to get some other easily identifiable disease that kills you before Alzheimer's does it's damage to avoid autopsy.

To show what I mean, here are the main ideas I've managed to come up with so far. None of these particular ideas are a standard part of a cryonics preservation package. Some are easier to implement than others, some are more likely to have an effect than others, some have potentially greater effect than others.
* Arranging for as much information about oneself (photo albums, emails, grade school report cards, etc) as possible to be placed on archival media and stored along with one's body. Reasoning: If the cryo-preservation procedure causes brain damage, and technology advances sufficiently before re-animation, then this information potentially allows for that damage to be at least partially reconstructed.
* Requesting additional data about the cryo-preservation procedure used on oneself be archived. Eg, requesting that, to whatever degree doesn't interfere with the procedure, it be videoed.
* Making arrangements for an animal body to be cryo-preserved with the same procedure one's own body was preserved with. A lab chimp would be ideal, but difficult to arrange for a number of reasons; more likely, a more common animal of around human mass would be feasible, such as a dog or goat. Even a few lab-rats might help. Reasoning: It gives future re-animators an additional opportunity to experiment with re-animation techniques, before attempting to re-animate a person.
* Noting down one's preferences and requests for future re-animators. Eg, from "I'd appreciate having a cat nearby to pet and calm down as I wake up" to "If you have to rebuild my body from scratch anyway, and it's within cultural norms, I would appreciate being gender _____" to "If you create a digital/electronic/computer/data copy of my mind, I would like a copy of that to be placed in offline, air-gapped storage, so that if every active copy of my mind is destroyed, there will always be that original backup available to re-instantiate myself." Or just more general ideas, such as, "My goal is to live forever, and I would prefer whatever means most likely lead to that happening to be tried."
I'm not nearly as creative as I wish I could be; so I'm hoping that the local group-mind here might be able to offer further ideas, or improvements or refinements to the above ones.
So: What extras can you think of?
