its easier in the way that you are not so anxious, not everything has to perfect, you are more laid back, but in terms of actual workload, its not twice the work, its a million times the work, and its not a case of having to split yourself in two, its much much more than that.
i find myself thinking one was a piece of cake at times, two is so hard work, sorry!
(but worth it)
