Hi..Squonk here...I was the one who recommended the Sol Lonzerote...I have two kids (2 and 3), believe me when we went to Sol Lonzerote back in April there were very little kids, apart from ours. I can't stand kids to be honest apart from my own! If you have an impression that the place is overrun by kids that's simply not true. If anything it's overrun by >60 Europeans. Talk to your traval agent; but from the email that you've sent Matagorda seems ideal to you. (PS For the records I have absolutely no affiliation whatsoever with Matogorada or the Sol Lonzarote).
