Help Daryl with His Cancer Dream

Daryl has metastatic cancer resulting from renal cell carcinoma for which there is no cure.  All treatment for him has been exhausted. He's now undergoing clinical trials in Bethesda at the National Institutes of Health.

As his wife, I'm now working on his "bucket list".  He is retired from the Navy after 22 years when he volunteered for several covert missions from his ship off the coast of Iran. His life was in serious danger during these missions.  He now yearns to visit a few Caribbean ports of call taking me on a cruise (something we've never done together) while he's still alive. 

His prognosis is not good at this point. I would so love for those of you who have some heart for an unsung hero to help me make it possible to take him on this cruise he so wants to become a reality for him.
