Plot hole: After running from the pirates, the two castaways almost stumble off a cliff. Unless they were running backwards, I'm sure they would have seen the cliff coming for a while, because when the camera zooms out you can see clear terrain for at least 20 metres until the edge of the cliff.
Factual error: As Robin and her fiancee are heading off to Macatea, there is a quick shot of an Aloha Airlines plane as it is landing. Aloha Airlines does not operate there or anywhere near there, but the movie was filmed in Hawaii so they apparently used what they had.

Continuity mistake: When Quinn and Robin are flying off the island in the DeHavilland Beaver, after replacing the Wheels with Japanese WWII floats found on the island, you can clearly see the brace wires in between the floats. These wires shouldn't be there, since they used bamboo to attach and brace the floats.
Continuity mistake: When Angelica is first approaching the charter plane, she has two bags - a leopard print bag and a white bag. Two shots later where she is sitting down in the co-pilot's seat, she only has the white bag. When she gets off the plane on the resort island, she has only the leopard print bag.
Plot hole: The morning after Frank and Angelica sleep together the hotel manager comes to her cabin to get her for the search. He says the helicopter leaves in 20 minutes. She wakes up Frank and tells him they have to go. The next time we see them they are eating breakfast. They only have 20 minutes but that is enough time for him to go to his cabin, shower, do his hair and change, while she does the same thing. Then there is still time to go to the restaurant, order food and get it. That is some long 20 minutes.
Continuity mistake: When Quinn and Robin first escape the pirates just after they row back to the island, they run up a hill for quite a bit. In a later shot they are running along a path close to the seashore, but immediately following that, they are at the higher elevation again as the pirates catch up to them.
