An Adventure to Disney World!

As most of you who are reading this already know - We are taking Ayden on a fun-filled 8 night/9 day adventure at the end of the month!
We are so excited about this trip to Disney World! 
We went on our 1st trip as a family there last Sept/Oct and fell in love with the place.  We decided over the summer to take another trip back and keep this one a secret!
Shhh! 
Nana is going with us for the first 5 days and we get to see Aunt Daphne and sweet Shyanne for 2 days while there.  It will be so much fun!
When we decided to take this trip we immediately knew we wanted it to be a surprise for little man.  He had such a great time last year and still to this day he talks about riding in the honey pot and teacups and seeing lots of fireworks.  He is saving all of his money in his "penny pank" for Disney.
(Of course we won't use it but it's still sweet!)
So after much brainstorming we came up with a treasure hunt of sorts.  Brian found a lady on Etsy that customized a map for us.  Then we decided we will give him clues along the way and the clues will be what mode of transporation we have to go on next.
(This is a very basic treasure hunt as he is only 3 1/2)

We start out in the car then go to the plane then take the bus to the resort.

As of right now we are planning on leaving the map on the front door step the day before we leave and tell him that someone left something for him outside.  Once he gets it we will explain that our adventure will begin the next morning and we need to pack our suitcase.
Once we wake up the next day we will have to go find our 1st clue (which is Papaw's clue).  We will meet up with Papaw and he will give him an envelope with a Mickey car pin.  Ayden will pin the Mickey car to the map.  Then we will get in the car.
While in the car Nana will give him his second clue.  He will open it and find an airplane pin and attach it to the map.  We will then go to the airport and get on the plane.
After we land in Orlando he gets his "mommy clue".  It will be a Disney bus pin.
We will then find Disney's Magical Express (the bus).

Here is a photo with the pins so you get the idea.

While on the bus he will get Daddy's clue.
In the envelope it will be 4 pins.  Once that represents each park - and believe me he knows what each one means.
Castle - Magic Kingdom
Silver Ball - Epcot
Hat - Hollywood Studios
Tree - Animal Kingdom

 If he hasn't figured it out by now we will then tell him we are going to Disney World!  I have a feeling he might figure it out when we get to the buses but it will be fun nonetheless!

I have been collecting little gifts that I plan on leaving for him in the room on the 1st day.  It will be a welcome gift from Mickey Mouse (his mystery friend that sent him on this adventure!)
Then we will have 9 days of fun/relaxing family time at the happiest place on earth!
