I learned a long time ago,when I missed my reunions,because my then hubby wouldn't go,that I will not ever do that again in the future.My parents are both dead now,and that opportunity for me is past.But not for you.If he can't go,you and the kids go.And stay for 3 days or so and enjoy the company while their still here and you can.I regret not going,and giving in.Now,I will never meet my dads side.Let your kids meet the family and get aquainted.It is much cheaper to drive,heck in our car we can drive to Kansas 1240 miles on just 6 fill ups.In fact we generally leave early am,and are there the next day by 4:pm Kansas time.Of course now,we're older,so would stop now at about 6 pm for a hotel and get rest and dinner.Now it would take 3 days and 2 nights.So,I say GO,your hubby will be fine,as he can hold the fort down.
