Hi! Welcome and congratulations!!!!
The best advice I've read or heard came from the Tour Guide Mike website. BAsically here's what he says:
THere is no restaurant, no ride, no show, no ANYTHING that's worth your whole vacation. So, if anohter hour on lines or waiting for an ADR you've heard you NEED or anything else is going to make you tired and cranky, simply don't do it. If that means you miss Fantasmic or LeCellier or whatever, it's OK-- they'll be there the next time (though it would be courteous to cancel any ADRs as opposed to simply not showing up.)
But it's unrealistic to think you'll actually see and do it all in one vacation and still enjoy that vacation, particularly a honeymoon.
So go, have a wonderful time together, and see and do what you can. Anything you miss will be there the next time you go.
Again, congratulations as you begin your life together!!
