Im looking at booking a trip to Marrakesh but probably going to the coast rather than staying in marrakesh itself- BA doesnt seem to be offering hotels outside of the marrakesh region so it would have to be a car package not hotel package.

I DO want the car. But if I am booking it as a 5 day package with CE flights I also want to be able to drink on the plane! Which means I wouldnt want to collect the car straight after landing. I am assuming that if i dont pick it up promptly it will be cancelled by budget/avis. But would i be able to check in with Budget/Avis and collect the keys etc but leave the car in their car park and not actually drive it out till the next morning?! or is this completely mad?
