What does each price actually buy?
€140 and €350 look like a wild spread until you see what each one covers. Kite Addicts and The Kite Bubble sell a single three-hour private session — one instructor, one student, school equipment. Red Sea Kiteboarding sells six hours over two half days, which is how most people actually learn, because a rest day between sessions helps more than a longer first day.
King of Lagoon sells the whole beginner path: four sessions, eight hours, the IKO licence and a day of rental afterwards so you can practise what you were taught.
What does bringing your own gear cost?
Rental after a course costs 90 € a day at King of Lagoon for the full kit, and Red Sea Kiteboarding has all lesson equipment in the price, with certification on request for a separate charge. If you are arriving with your own kite, ask about beach access when you book: Kite Addicts charge 10 € a day for it.
How big are the groups?
Kite Addicts and The Kite Bubble are one-to-one by design. Red Sea Kiteboarding caps a group at three and charges €175 per person instead of €240 if you bring the group yourself — two friends learning together save €130 between them.
Important
lessons are scheduled around the wind and the time is agreed with you, so leave a day or two of slack rather than booking the last morning of the trip.
