In Central America, island hopping hangs on boat schedules as much as flights. Morning ferries run more often on calmer seas; afternoon wind can rise. A “three islands same day” plan usually dissolves on the water.
A dry bag, motion medicine, and flexible lodging cancellation are lifesavers. Honor sunscreen rules near coral and mangroves. Local fishing boats may look cheap—ask about life jackets.
Coastal culture shifts by country; there is no single Caribbean cliché. Two nights on one island teach more than a blur of hops.
