Erika Tiffany Smith to the Rescue

Will the castaways be rescued by a rich socialite who wants to turn the Island Into a resort and happens to fall in love with the Professor?

Mrs. Howell is jealous of Erika Tiffany Smith because her name appears before the Howells in the social register!

Another silly epsiode, although Erika agrees to go into partnership with Mr Howell to build the resort. At the end, she apparently changes her mind, saying only she has spent time with some charming people on a island (without giving their names!) Likewise, her logbook isn't any help. Not only is there no latidtude and longitude given, its written in Hungarian which the US Navy cant read! (This is injoke guest-star Zsa Zsa Gabor comes from Hungary)

The 2nd movie made after the series ended "The Castaways on Gilligans Island" does show the Island being made into a resort!
