Christmas, as we all know, is a huge holiday almost everywhere and Christmas in Phuket is no different. One small difference, or it should be said as big difference, it's meant for kids but Phuket is Disneyland for adults so everyone is expecting to have a present.
Fact is, many places add the Christmas tree and decor so visitors, especially the kids that come along with family vacationers, have a little cheer to see the lights and tree beside the sea and sand everyday.
Most hotels and other businesses would have also added some form of Christmas decor to keep in line with the festive period as it is also the peak season and many places raise prices to earn more. Most larger hotels also have a "must attend" lunch or dinner that is included for people that book rooms within these hotels. Don't be surprised as it's standard practice all over and if you booked your Phuket hotel online, it would have stated so.
Nonetheless, if you have never experienced Christmas in Phuket, you are in for a treat. I have to emphasize, guys especially, are allowed to be naughty or nice.
