Welcome aboard, Dawn! You must have a magical Land and Sea vacation with Disney planned if you're asking about the park schedule and the cruise activities! How exciting!
The schedule of fireworks, parades and character greetings at the Magic Kingdom is available on the
Walt Disney World resort website's Park Schedule page. On the top left, you'll be able to view the drop down menu under "Park Hours" to view "Park Schedule". It's a great idea to plan out your time in the park so you can make the most of every moment and not feel pressured to run from one thing to the next.
Disney Cruise Line does not publish their Personal Navigators prior to the cruises, as events and activities are always subject to change. That being said, if you do a search for Disney Cruise Line Personal Navigator on Google, I bet you'll find a few Disney fan forums where guests who have cruised recently may have posted their navigators. Though it won't be exactly what you can expect on your particular sailing, it is at least a nice way to get a feel for what the navigator looks like and what activities have been offered in the past.
Though schedules are always subject to change, most likely you can expect to see the following movies playing on your May 5th sailing on the Dream:
The Avengers
Brave (2D and 3D)
The Odd Life of Timothy Green
Finding Nemo 3D
Frankenweenie
Wreck-It Ralph
Lincoln
Oz the Great and Powerful
Have a wonderful cruise in just a few weeks, Dawn!
