Kimberly,
Since April dates for Extra Magic Hours are not yet out, what I would recommend you do as a general plan is this;
- April 3 – Arrival Day / Resort Exploration / Dinner at the Polynesian
- April 4 – Magic Kingdom
- April 5 – Animal Kingdom
- April 6 – Epcot
- April 7 – Magic Kingdom
- April 8 – Departure Day
I really think you should use your arrival day as your resort exploration/Polynesian dinner day. If you were to rush off to a park, at best you are getting there having already missed several hours.
Instead start your vacation off with some
RELAXATION! Settle into your resort and explore there a bit. Find somewhere fun for lunch (I am glad to make recommendations!). Do some more resort exploration, or maybe hit the pool? Shopping at Downtown Disney?
Then head over early to a dinner at the Polynesian. Get a drink and walk down to the beach. Explore. Dine. Catch the Magic Kingdom fireworks from the Poly beach after dinner.
That is how to start your vacation off right!
Have a magical vacation!
