5khours, thank you also. I'm not so much concerned about line-of-sight privacy as not having to hear noise (crying/screaming children - or crying/screaming adults

), so that's the reason for my "location of the casitas" questions. I already know I'll be happy with the diving, since I am everywhere. And meeting the monitor lizards sounds very fun too!
But regardless - I'm going in early June, based on all the wonderful info this group has provided - and will take many photos to add to the many already posted here.
