This year for the first time I rented a holiday villa on a Spanish island. After reviewing literally thousands of villas online, in January, I finally settled for one which had a walled garden. I have two toddlers (3 years-16 months) so this way it felt safest. Lo and behold when I checked the villa last week online (it´s on tripadvisor and airbnb) it suddenly has a big swimming pool in the garden. They must have installed it in the last months, after my booking. Now I´m already laying awake at night by the thought of them wandering off while I´m cooking/sleeping/etc. and falling in. We will be two adults and four kids but we now will need to be vigilant all the time. I think my older kids (and husband) will be happy with the pool but would you know any way of providing a bit more security? A school mum said they had used pool alarm bracelets, any experience with those? Thanks for reading this far!
