This happens - living close to Disney with most of the homes having a pool and many tourists from all over the world who think it will never happen to them . It does! This is fantastic but should be a last resort with pool alarms and safety gate a must.
If you rent a vacation home always, always keep the door alarms on if you have children. They are there for a reason and it is against the law to switch off or disconnect. Have fun in the sun but be safe!
