I really agree with Bo Man on how to get the best from a surf camp, aqualifies instructor who can handle a genuinely developing surfer rather than a raw beginner in a mass class.
One who can give you what you need rather than having half an eye on the girls in Bikinis.
When you find one suitable, do a few things : if they have a selection boards try an occasional surf on another board , but if as I guess you would , hit the sessions on your personal board as much as possible.
Some schools video their students ( for a fee) but it is a great way to really find out where you are in your progress and sort the useless and ugly bits of your surfing out. This is when your self critique is really valuable.
Have a great trip back to Morocco, sweet waves and especially after North Sea cold and sloppy.
