(1) CARRY BUG SPRAY
Major tourist areas, such as Bangkok and Phuket, have very few cases and are considered malaria free. However, malaria is still a problem in rural areas. Carry repellent that contains a high percentage of DEET. Also consider malaria pills.
(2) BRING HAND SANITIZER & TOILET PAPER
Western toilets are more and more common. But the Asian squat toilet, a ceramic platform mounted over a hole in the ground are common in lesser-visited towns in rural areas. If this is your first experience with such toilets, take note: near the toilet is a bucket or sink with a small ladle. The water is for cleaning yourself and flushing the toilet. Many public washrooms have one Western toilet. Always carry a pack of tissues with you since toilet paper is usually not provided.
(3) DON'T DRINK THE WATER
Don't drink the tap water here, even in the major hotels. Most hotels provide bottled water; use it for brushing your teeth as well as drinking. Most restaurants serve bottled or boiled water and ice made from boiled water, but always ask to be sure.
(4) LEARN TO SAY “HI” AND “THANK YOU”
Make the effort learn a few phrases and words.
Here’s how to say “thank you” and “hi”.
If you’re a girl: “Kap-kun-kah” (kop-coon-kaaaaaaa)
If you’re a boy: “Kap-kun-kap” (kop-coon-kop)
If you’re a girl: “Sawadee-kah” (sah-wah-dee-kaaaaaaa)
If you’re a boy: “Sawadee-kap” (sah-wah-dee-kop)
(5) NEVER PAY FULL PRICE
Don't be shy about offering a lower price than advertised for goods. Start by offering 50% to 70% of the item's stated price and increase your offer as the vendor decreases the sale price to reach an agreement.
