Why were they carrying luggage
I watched this movie a couple of years back and I had to question why Skipper and Gilligan were carrying luggage. And why was Gilligan still subservient to Skipper. Early in the movie Howell announced he was turning the island into a resort and they would all be equal partners. Which would mean that all seven of them would be owners. Owners would not carry guest luggage that is what employees do. Plus Gilligan and Skipper were not young men and I am sure Howell would not want to pay medical bills if they got hurt.
And since Skipper and Gilligan were equal owners Gilligan was no longer Skipper's employee. By all rights when Skipper told him to do anything he could have told him to get lost.
