The AlphaGraphics Gold Circle trip during March 2015 was to the Dominican Republic. We stayed at Paradisus Resort in Punta Cana. It was very nice and very resort-like. Nice beach. Great coffee.
The only day trip was to the old city area in Santa Domingo. Long day, but worth seeing. Well preserved/1500s! Ancient by western standards – the oldest area in the Americas (non-native). We visited Columbus House (his brother was the first Governor), the old cathedral, Columbus Lighthouse monument and wandered about the city a bit.
