For family vacation, I would recommend Nusa dua ( tanjung Benoa ) as well.
, if you would like to stay away from the chaos , hastle and bustle in Kuta and Legian etc .
Nusa Dua is the area with lots of five star luxuary hotels , but there are quite few lovely villas and hotels between them, which offeres more friendly atmosphere and personalized service !
Compare to Kuta and Legian ( main town ) everything is little bit pricy , but all restaurants offers free pick up and drop off service for guests, lots of shuttle bus service.
Tanjun Benoa beach has lots of water activities , all day trip leaves from the Benoa harbour too.
I would like to recommend this place especially ,
I had been staying this hotel over the years ,
Kinds Villa Bintang - Beach Resort with garden and SPA
Small , reasonable, great location ( Private beach is on your door step) , nice pool bar, all staff works there are great.
Have a great holiday !
