Before the first day
Check arrival times and leave enough margin before a boat departure. Compare an overnight trip with separate day outings, including meals, guides and the time spent returning to the same base. Confirm the actual cabin layout if you plan to sleep aboard.
Day one: settle into the region
Keep the first activity manageable after travel. Discuss one suitable beach or water stop with the provider and use the first evening to understand the route. Treat a late arrival as a reason to simplify rather than rush.
Day two: prioritise the visit you came for
A ranger-led wildlife visit or a viewpoint walk deserves its own block of time. Check park access and follow the local guide. If your group also wants diving, make the programme suitable for their qualifications and recent experience with a qualified operator.
Day three: leave room to return
Choose a final activity that fits the disembarkation and onward-travel plan. Do not depend on visiting one precise site before a tightly scheduled flight. Conditions may alter the order of stops.
What to leave out
A long list of named sites can hide the time needed to move, change clothes, eat and rest. Ask which two or three experiences the provider would prioritise for your group, then agree alternatives.
