1. Build the route around transport, not wish lists
Start by checking actual nonstop flights and ferries between the islands you want. Two places that appear close geographically may require a connection through a third island. Route maps change, so verify schedules for your travel month rather than relying on an old blog. If a segment requires most of a day, ask whether the extra island is worth the lost beach or exploration time.
2. Use island groups to simplify the trip
Routes within the Lesser Antilles can sometimes be combined efficiently, while the Greater Antilles and southern Caribbean have their own flight patterns. Ferries are especially useful on certain local pairs and archipelagos but do not form a universal Caribbean network. Choose two or three islands with logical links rather than trying to collect countries.
3. Allow for separate tickets and baggage rules
Regional flights may be booked separately from the long-haul ticket. That can mean no protection if an incoming delay causes a missed onward flight. Baggage limits on small aircraft can also be stricter than on transatlantic services. Leave generous connection time or an overnight buffer, and check the total fare after bags rather than comparing base prices alone.
4. Immigration resets at each jurisdiction
Moving between islands can mean entering a new country or territory each time. Passport validity, visas, onward-ticket expectations and permitted stay length can differ. A visa or residence permit for one island does not automatically cover the next. Check official entry rules for every jurisdiction using the passport you will actually carry.
5. Weather can disrupt sea and air links
Hurricane season and tropical weather deserve respect, but even outside major storms, high winds and rough seas can alter ferry or small-plane schedules. Build slack before the international flight home and avoid a same-day remote-island connection when missing it would be costly. Travel insurance should cover the risks that matter to your route rather than simply being the cheapest policy.
6. Give each island enough time
Changing islands involves packing, transfers, check-in, immigration and new accommodation. A two-night stop can easily become one usable day. For most trips under two weeks, two islands often feel better than four. Longer stays let you compare different cultures and landscapes without turning every third morning into a departure.
7. Choose islands for contrast
Island hopping is most rewarding when each stop offers something different: a walkable historic city after a resort beach, hiking after diving, or a quieter island after a busier nightlife base. Combining near-identical resort experiences adds transport cost without adding much to the trip. Use food, language, landscape and local culture as route criteria, not only beach photographs.
8. Finish near the strongest flight home
Where possible, end on an island with reliable long-haul connections or return there a day before departure. Open-jaw international tickets can also reduce backtracking if the airline network supports them. Compare the full itinerary before booking individual hotels, because the cheapest room sequence is irrelevant if the inter-island transport becomes expensive or impossible.
