This would be a useful inclusion in a will. For example, add provisions and funds to transport you to another facility should the one you are in fail, and to another if the second is not available, ad infinitum until permafrost interment.

Eric DeMar did something similar in his will, to ensure his parents (Who'd been cryopreserved by Trans Time in the seventies) would be transported to the CI facilities. A very good choice, considering Trans Time's policies.

A separate decision tree may be included to cover alternatives to cryonics, if the entire cryonics decision tree is exhausted of possibilities: Brain-only chemopreservation as the first alternative, high-temperature vitrification as the second, and so on and on until you decide to simply have your body cremated.
