Hi, just wondering if you were able to get a definitive answer regarding your airport dilemma departing pre dawn the day after Nyepi?
I noticed you also posted on another forum and I replied. Most people just don't seem to get the point that you are leaving before 6am. I was talking to a long time Bali traveller and friend last night and she said that years ago, passengers arriving or departing during Nyepi were transported by shuttle directly to the airport or hotel.
Perhaps you should email your hotel in Bali and ask them if they will be able to get you to the airport. I am very interested to know the outcome for future travel.
Regards
Angie
