Strangely....the lines were non-existent.
The only wait more than 5 or 10 minutes was for test track.
The weather was great .....low 80's the whole time. Only 2 short showers in 7days.
However .....the last couple of days we were there seemed a bit busier.
With Easter being later I think people are going to Disney later this year. MK seemed to be the busiest of the parks. We really didn't even need our ps's.
Kiely...you will have a great time. I think you are gonna luck out with great weather and short wait times also.
My only tip....if you are using wdw transportation.....avoid the mass exodus to MK in the mornings. If you wait a little later...the busses will be much less crowded.
