In all the years I have been coming here I have never seen the traffic this bad. Xmas/New Year is always busy with locals also having their holidays at this time and bring cars over from Java however this Xmas is the worst I have seen it. Do allow enough time to get to the airport as drivers are commenting it is taking 2-3 hours at times to get to the airport and the same to Nusa Dua. Even bikes are not getting through the traffic. Drivers are also having problems reaching hotels to pick up guests. Just keep this in mind if travelling at this time. Enjoy!
