I found a web site with a "how to make a christmas advent calander" but all you need to do is get rid of christmas and add disney stuff to it
Box Advent Calendar
Materials Christmas fabric, card board, 24 match boxes, foil, string

Decide how large your calendar will be. You will need an area about 3 foot square for the boxes. To get an exact size, lay out five boxes in a row.

Allow enough space in between for each box to be opened. Measure for the width of your calendar and add about 2 inches on each side. For the height, put five boxes in a column with about an inch separating each box. Measure the height and add 2 inches for the top and bottom.

Cut out the cardboard in the finished size of the calendar. Then cut out the fabric 1 inch larger.

Glue the fabric to the cardboard and wrap the edges over so that none of the cardboard shows.

Cut out 25 foil rectangles the width of each match box and long enough to go all the way around the match box. Glue the foil to the match box. Make sure that you can still open each match box.

Glue the boxes on the calendar in 5 rows of 5.

Fill the boxes with candy, coins, or notes.
This activity will take an afternoon to make, but you will be able to use it for years to come.
I hope if you make this it comes out well... im not totally crafty as well unless i have a pattern to go by... so good luck
