I thought it might be helpful to look at the times the parks are opened when we are there.
WDW Times for June 7
Epcot:
Future World, 9 am to 9 pm
World Showcase, 11 am to 9 pm
Disneys Hollywood Studios: 9 am to 9 pm
Animal Kingdom: 9 am to 7 pm
Magic Kingdom: 9 am to 10 pm
Since the Magic Kingdom is opened the latest, I guess it would probably be good to end the day there for those of you who have the extra energy!
Betsy, Getting from Epcot to the Magic Kingdom is easy. Just hop on the monorail to the Ticket and Transportation Center and then switch over to the Magic Kingdom Monorail. Shouldn't take you that long at all.
My favorite rides at Epcot are:
Test Track - Get a Fast Pass
Soarin' (but I believe you have that in California)
Journey Into Imagination - never a wait but it's so cute with Figment
Spaceship Earth (usually packed when you first enter the park. Never much of a line later in the day. We usually go there on our way out.
The Living Seas building is really nice. Go find Nemo on the ride and then head over to Turtle Talk with Crush. It's hilarious.
I also really like the Universe of Energy with Ellen. Really funny, but it's a long show/ride.
Mission to Mars is great! But if you tend to get sick, you can opt for the non-motion ride.
While walking around World Showcase: Mexico has a cute little ride and it moves quick.
Norway has the Malestrom. There is usually a line. Last time I was there I walked out. People love this ride and I really just don't see the point of it. If I have to wait more than 10 minutes I leave. Oh, and if you do get on the ride, at the end they'll move you into a "theater". There is a door on the far side. Keep walking out the door unless you want to sit and watch a 6 minute movie about Norway.
I love walking around World Showcase and going into the stores and taking pictures and eating!
Well, those are my personal thoughts on Epcot!
