General Info
Drinking Water
Drinking water straight from the tap in Phuket is not advisable. Most mid range and higher hotels provide one or two bottles of drinking water per day. It is best to get in the habit of drinking bottled water especially if you will be visiting rural areas or other countries in the region. Always take bottled water with you when you are out touring.

Electricity
Thailand's voltage is 220 AC, 50 hertz using a two round prong plug. Some of Phuket's larger hotels may be able to provide an adapter plug and have special outlets for shavers in the bathroom.

Smoking
In the last few years Thailand has passed several strict anti-smoking laws in an effort to control or stop Thais from smoking. Those under 18 years of age can not purchase tobacco products and smoking is no longer allowed on television (advertisements or shows). It is also illegal to light up in many indoor public areas including air-conditioned restaurants and barber shops.

That said, smoking is still quite common in Thailand. Most large hotels offer non-smoking rooms on smoke free floors. If this is a concern to you (either way) make sure to have your preference known when making a reservation or entering a restaurant.
