I am not sure about zero entry, but I do know that the slide has a minimum height requirement of 48 inches tall. We have a daring 2 year old who went down the water slide with us at Regal Palms and loved it this past February. So when we started looking for villas for this coming February, I immediately considered Windsor Hills. Luckily someone happened to post the height minimum so we decided against WH. I am glad they have their safety requirements, but I am also glad I knew ahead of time so I didn't have to listen to my DD beg to go on a slide she is too small for.
