Query: Really Fun

I liked this film a great deal. three couples meet for vacation during each season of the year. Each one is totally different. Alan Alda is the intellectual that thinks too much. Jack Weston is the cheap dentist that fights with his wife (Rita Moreno) all the time while she keeps saying that she can't help it because "I'm Italian." The other couple is kind of sexually adventurous and the wife is a big flirt, especially with Alan Alda.The couples go through all the ups and downs that real friends do, from big fights to real touching moments.
