Hi Kay, We need more details to answer the question properly. Are they at a rectangular table with no one on the ends? Are the 'sides' different in any way? Or at a circular table with a head chair or with no 'head' chair? These thing s make a difference. Suppose it is just an rectangular table and people sit along the sides and there's a big picture on the wall along one side. There are 5! =120 ways to order the 'couples' along a side and this needs to be combined with 2 possibilities for each couple  which one of them is on which side (near the picture). In total 2^{5 }(5!) = 32 120 = 3840 ways. Penny
