Although the lazy river at Villa la Valencia could entertain kids for days, there is too much adult behavior in common spaces for it to be kid-friendly, in my opinion. The lazy river winds through a resort filled with adults drinking all day.  During my time floating around the Villa La Valencia lazy river, I saw behavior I would not want a child to see. Most problematically, a drunk man exposed himself, within my view, on the banks of the lazy river (to a woman on a balcony above, who was also exposing herself). While I hope this behavior was limited to my trip, I suspect that the recipe of all-inclusive drinks combined with the simplicity of purchasing this vacation package through Costco Travel often results in overindulgence or poor decisions- without checking if children are nearby.
