In a large bowl, beat together granulated sugar, brown sugar, and butter until fluffy. Beat in vanilla and eggs until well blended.
In a separate bowl, stir together flour, baking soda, and salt. Combine flour mixture with sugar mixture.
Stir in chocolate chips, coconut, pretzels, and M&Ms. Refrigerate for at least 30 minutes.
On ungreased cookie sheets, drop dough by rounded tablespoonfuls 2 inches apart. (I line mine with parchment paper for easy removal)
Bake 8 to 10 minutes or until light golden brown. Cool 1 minute; remove from cookie sheets to cooling racks. NOTE: Do NOT overbake. They're ready when some just start to brown slightly on the top.
