A word of warning and sad to hear.
Some close friends of ours were in Bali 2 weeks ago, for the first time with their 2 daughters 26 & 18 & son 20. The 2 daughters were sitting on Kuta beach one evening and felt secure that there was good security around and got involved in a conversation with one of them. Not paying attention to their surroundings, they were distracted during the conversation and after the " security guy " dissapeared in the crowd, they sat down and after a short while, discovered that their bags had been stolen with valuables, money and keys to a hired scooter.
This would not be the first time this has happened, so please be aware of being anywhere ( beach, nightclub, bar, restaurant )and leaving bags or valuables out of your eyesight. They enjoyed Bali, but were saddened by this happening and not keen to go again.
