I am among the many who wish your circumstances were different and I wish you the best moving forward. In the event your proactive options regarding your accounts aren't comfortable or efficient ones for you, isn't it true that upon the death of a spouse, miles/points can be transferred to survivors' accounts once certified copies of death certificates are filed with airlines/hotels? Pretty sure no miles or points balances are reduced in the process. As such, I'd submit giving some thought to using as many of your accounts now for whatever travel you are able to manage. In the meantime, contact the hotels/airlines for the addresses your spouse would need for mailing in documentation in accordance with their guidelines.
