For Lake Garda I would recommend this outfit Rick:
scuola kitesurf sul lago di garda
It's not far from Malcescine and if you are camping there is a handy little campsite at Assensa.
The morning wind is best for you, get up early, have a blast, the wind is gone by midday so the rest of the day is freed for family stuff.
The beauty of their set up is that they will take you out on to the lake, find the wind, launch you, look after you and bring you home.
Yes, some nutters launch through tunnels, saw it myself.
Had ten days there some years ago, the prices have gone up since then but a 50 Euro hit for two days service still looks good value to me.
