Eastern Caribbean Antilles Shore Things

I’m going on my second VV cruise in January and it’s the Eastern Caribbean Antilles itinerary on the Scarlet Lady. My first cruise was the Dominican Daze itinerary on the Valiant Lady so I’m familiar with the shore thing offerings for Puerto Plata and Bimini. However, I’m wondering about the shore things for San Juan and St. Croix. I’m interested in the Caffeine and Cobblestones walking tour in San Juan and the Better Cocktail Better Planet Class in St. Croix. Has anyone ever done either of these and have feedback on them? Or does anyone have recommendations on other VV shore things to check out?
