Last Resort (1986)

Last Resort takes place at "Club Sand", which seems like the idyllic vacation spot for Chicago businessman George Lollar (Charles Grodin) to take his entire family for some fun in the sun.  Instead, it's bad accommodations, weird and unhelpful staff, and nudists flaunting eyefuls of furburger and flappy phalluses.  Everyone but George seems to be making the most out of a bad thing, but Charles Grodin does his best-exasperated impression of himself and can't get over it.  This sandy concoction gives us a few memorable sexy scenes though, including a shirtless Charles Grodin, a young and sexy Mario Van Peebles in a speedo, and Eduardo Richard as a nudist who shows you his caboose.  It's a classic romp that'll make you remember that nudity was borderline mandatory in 80s movies!
