What's the first thing you do?

You arrive at Disney.  Your anticipation mounts at you take the bus, ferry or monorail into the Magic Kingdom.  How do you feel?  What do you see?  Hear?  Smell? 
For me?  I see beautiful flower arrangements and people trying to get where they are going.  I hear the Disney music, the train bell clanging and lots of chatter and some kids crying.  What do I smell?  Mainly just the flowers. 
You won't see garbage or grumpy employees.  You won't even be able to see Main Street right away.  You won't smell food from the restaurants, and dirtiness of any kind.  You won't hear screaming from the attractions.  (Not even Tower of Terror until you are closer)  and may not even hear the monorail until it's almost right over your head.  Disney has done an amazing job of letting your senses only experience what they want you to experience at that time. 
I always get this huge sense of excitement and anticipation.  It may be years before we go back, but when I'm there, it's like we never left.  Cast members smile, you try to find the quickest turnstyle, get your bag checked, grab a map and off you go. 
If you're following a tourplan, which I highly suggest, you race to get your fast passes and then wait in line for your first ride. 
My kids usually can't stop talking, my older two have their pin lanyards on and are checking out cast member pins, while my husband and I are trying to hurry them up. 
We usually walk by Goofy, a Princess, or Pluto on our way.  A quick and fleeting thought comes over us.  Do we stop to get a picture?  Nah...we have more important things to do.  Fast Pass - Fast Pass - Fast Pass.  We have learned we DO NOT go with out a touring plan.  What is a touring plan you ask?
Well it's a detailed plan of your day.  What ride to go on when, and what fast passes to get. 
Now this changes depending on the ages of your kids, what park you are at, and how many days you plan to be there.  This has saved us so much time waiting in lines.  Now you do have to be slightly flexible.  Sometimes you walk by Pirates of the Carribean and there is a 5 min wait.  It's not suggested you go just yet on the plan, but why not?  It's a 5 min wait.  Which usually means you can walk right on.  Another great Disney surprise.  Many times, but not always the lines are shorter than the time sign reads.
