In case you haven't bought your tickets yet, you should consider looking at the
ticket prices at
Undercover Tourist. You can usually shave a few bucks off the price of each ticket compared to the Disney prices, and you can even get the ticket numbers emailed to you if you're close to your 60-day window for booking Fastpass+. I used
UT to purchase tickets for my upcoming trip and thought they were excellent to work with.
To save a few extra dollars, subscribe to the
Mousesavers newsletter. Their monthly newsletter includes a special
Undercover Tourist link that gives exclusive ticket prices just to Mousesavers members. The newsletter is free and includes tons of other savings opportunities in addition to the tickets.
The OPs have done a good job on explaining how you link all of your trip elements to
MDE. Once you set up your profile it's a pretty easy experience! (As someone who also booked through Orbitz - make sure you use either the 6-digit hotel confirmation code from your Orbitz confirmation or the 12-digit confirmation number from Disney Destinations into MDE. The Orbitz confirmation number, 15-digits or so, will not be recognized in MDE.)
Good luck and have a great trip!
