I hope you do as there are some nice beaches that i would love to hit. Dominican Rep, Jamaica and such sort of worn thin on me. Be great to hear how it goes!
I have talk to canadian air transportation last night , they said there should not be any problem , but to check with the airport in cuba. I will also try to call the ambassy. Will make some more phone calls on it , i might also contact the resort. I have seen people with metal detector on the beach in cuba before i was in the hobby. That is how i got the idear to do some.
Got back from cuba yesterday , while i was up there i ended up visiting beach of 3 resort and talking to some of the staff who work the beaches , i was asking if they saw anyone with a metal detector on the beach and most of them told me on and off they saw some tourist on the beach using them.
