Bad News!
Afraid when your dead,your dead.Unless you believe in the afterlife.Getting serious I don't think there is a time age concern when you visit the world.On our first ever visit I was looking all around at various things,trying to take it all in.Couples with " just married " Mickey & Minnie hats,families with very young children,like one year old tots,then there is the teenagers with their moms and dads,but the best I saw were this old couple,Iam talking 80+ just sitting together with ice creams,enjoying the sunshine and people watching.I looked at my DW and said, " that will be us someday "she just smiled and said " hope so ". So to your question.No, there is no age concern for visiting WDW.:wave:
