Jane,
Virtually no noise at night , these apartments are all privately owned, often occupied by their owners and there is no organised entertainment to keep you up all night. Most will be occupied by several generations of a family. You will have a fantastic time and so will your parents
We stayed at Sangrilla from our daughter being 10months to 7 years before moving over to some of the other buildings ...... mainly for more space ( 4 bed apartments with 2 or 3 bathrooms ) as we always seem to get various members of our extended family deciding to join us.
You will love it, if you decide you want some organised childrens entertainment one evening, wander up the road to the Ora Playa ....... the entertainment is typical holiday tacky stuff and all based around the pool .... the kids seem to love it and so long as you buy a drink the bar staff don;t seem to mind non residents.
Also, if you can get the tiny ones to sleep in their buggies, there is usually a live band playing at the bonanza ( almost opposite ) on a friday evening ....... entertainment free providing you eat in the restaurant, another option is the flamenco dancing ( think Tuesday ) at the Ila d'or ....... don't be frightened off by the upmarket staid impression it can sometimes give, we have always found that providing you can keep the kids seated, they are really welcoming ( other alternative is to banish the littlen's and Dads to the beach outside whilst the rest of you enjoy )
Out of interest , when are you there ?
