Whatever you decide to do you should do together as a family. I do not think splitting in early and late groups is a good idea. Yes you want to enjoy Disney but you want enjoy each other in Disney as well, isn't it a point to go together in a first place. Do first day late, let them sleep, see what happens but if they still want to sleep in, go to parks later together, do not split your family in groups. And both of you can compromise, do half of the vacation early and half late.
I agree with this. Family unity, especially with a blended family when some have not done Disney before, is more important than doing TSMM. If they are night people they can do evening EMH, the lines shorten after the parades/fireworks anyway. Discuss this with your wife ALONE first and see how she feels about splitting up, but IMO you as the seasoned Disney veteran can give up the rope drops for the sake of family bonding and togetherness.


), we're more of the commando pace type, which may be why it works out for us, but even during spring break week, the earliest we'd get to a park would be about 11am and we never missed an 'e-ticket' attraction.
