Were you supposed to fill it in again afterward, or were there just all these dug holes all over the place from various visitors?
The holes didn't last very long @indigoocean because they were dug in sand. As soon as you got out they started to fill in again because of the moving water.
On the other hand there is some safety concern in that situation that there isn't at a spa.
It was in my younger, traveling days. The longer I was away the more relaxed I got and the less I worried about safety.
Also, I would say that culturally I think about safety less than seems to be the case in the American culture. 😊
