Ahoy, Karla!
What an amazing itinerary you've got planned for your vacation. Land and sea vacations are the best of both worlds - and you won't go wrong going with this Disney combination!
Memory Maker will only work at Disney World and is separate from the photography package that is available on Disney Cruise Line. These 2 packages are not combined, so you'll have to look at purchasing a separate package for land and for sea at the moment.
If you are interested in purchasing a photography package while on your cruise, you can purchase this in advance by going to the My Cruise Photos site link that is on DCL's
Photography page. Choose your voyage, then pick the package you'd like. You'll even qualify for a discount for pre-purchasing a package on this site. Whenever you see a PhotoPass photographer on your cruise vacation, just get your photo taken and they'll link all photos through your Key to the World card. To view your printed photos onboard, just go to Shutters by mid-ship.
Hope this helps, Karla. Do let us know if you've got any additional questions that we can answer for you.
Happy planning!
