Hmmmmmm .....
Others may disagree but I have to say no .... that you will be REALLY pushing it. Spectro gets very crowded (so crowded I have yet to see it :-( ..... poor me!) It may be hard to meet Dad and get a good viewing spot. Like what if the veiwing spot you choose to meet at is mobbed? Or is dad willing to stake it out for an hour and save you curb?
ALso, at times with a 7:00 PS you may not be seated until 7:15 or something like that. You get the next available table and sometimes that means you still have to wait a few minutes. Then get seated, order drinks, eat dinner, eat dessert .... photos ... autographs ... alot to try to do and be in a rush! Then figure you have to leave, get on the monorail, come back through the gates into a very crowded main street and find Dad.
Will you have walkie talkies?
I'm also not sure what and where they rope off stuff but I'm sure someone else can help you with that. I just know it's quite a crowd at parade time!
You could give it a go if Dad is willing to get to MK EARLY and save you spots on the curb in a very specific place so you can find him.
Good luck!
