I echo that 5000 is pretty close. Brunches etc are extra to that. On the topic of food, I have noticed in the last year that there are many little Web based stores selling 'food from home'. These cost pretty close to double what they cost in home countries. I always have a chuckle when I pick up something at the supermarket and the box has preprinted price on it. An example is the £1 fish fillets that sell for 20 dirhams.
As for kids activities, 1 child for 2 X 1 hour tennis lessons a week for 4 months is 2015 dirhams. Convert that as required.
