History
Memorial and historical sites require respectful behaviour and a separate assessment of content for children. 1
Nature
Arrange conservation visits through an authorised channel; wildlife sightings are not guaranteed.
Departure
Avoid linking the final island activity to a tight, separately booked connection.
How to use this plan
Choose one main outcome and identify what it actually requires. Remove optional stops before sacrificing rest or travel buffers. Confirm current access, service availability and prices with the venue or provider rather than relying on an old review.
