Our charter company (TMM) had bags of ice and blocks for purchase at their base. We provisioned ourselves in person at the big Riteway. The shelves were a bit picked over and bare on a Saturday night mid-March. Maybe just bad timing on our part? We provisioned alcohol & drinks from Caribbean Cellars - wish I could say it was great, but they were out of a few things (most key was gallons of water) and we didn't know that until they showed up at the boat with our order.
