Whilst this should probably have been posted on the Condado community page, I'm afraid you may be fighting a losing battle. Some parents (regrettably mainly British although I wouldn't want to generalise) seem to think their kids are on holiday and can do what they want as long as the kids don't bother them. I remember staying in a hotel in Majorca and Brit kids were left to run riot. One woman used to go out to the disco across the road and leave here 4 or 5 year old in the room by himself. Nursing a hangover the next day, she told the kid to %^$% off and leave her alone while she slept by the pool. Kids were abusing staff, running round the hotel unsupervised and parents totally ignoring them.
Just recently, we have a "no-balls" rule in the pools but it is largely ignored. If it's just a small one and kids are playing, nobody seems to bother. However, two kids, with their parents lying by the pool. brought one of these huge ones in and started annoying the other swimmers. Quite rightly, the lifeguard told them to remove it and got a mouthful from the parents. The kids simply moved into another pool until told to move from there.
It's a sad fact of life that many parents don't give two hoots about their kids. Obviously underage drinking is a serious breach of the rules but we also see that at our local pub, again (sadly) accompanied by their parents.
