I'd be stunned if you find tourists who respond to an offer to join you for cribbage on this forum; I'd focus your efforts on cribbage clubs on the island.
The Pacific Club explicitly calls out cribbage as one of the games played by regulars:

There was also a Paradise Peggers Cribbage Club that seemed to be pretty active before COVID:

I suggest emailing/calling the POC to see if they are still getting together. Note, while this organization's last Facebook written post was in 2018, they posted a photo just last year, which makes me think they are still active but just not posting on social media much.
If you're able to find a U.S. submariner community on island, there's a good chance you'll find cribbage players that way, too.
