How do you think it will be? What emotions arise when you think of the chill day with some weed, or the start of festivities with the L? Do you want to roll down a hill when you roll on some rolls?
If it were me, I'd just do all three at once and go looking for some cool cats who have some psychedelics for the other days.
Dont do what that other clown said and take all your drugs in one sitting.
Keep to your plan and take your drugs in that order, and youll have some awesome stones/trips/rolls to last you the whole weekend. Also an acid comedown and MDMA comedown overlapping would be unpleasant. The day of stoned recovery between trips is a great idea.
