Some of these apply more to Hua Hin than Thailand in general and some do apply to the entire country (or even all of S.E. Asia) and several items on the lists are probably only applicable to an American. Both lists are what I could think of at the moment and are by no means exhaustive. As you can see the dislikes list is much bigger that the likes list, hence my misery there and eventual exit back to the homeland.
Dislikes during my "ten year retirement" there or what I don't miss:
1. Climate, more specifically the constant heat and humidity with no apparent change of seasons ever.
2. The cost of trying to keep cool in that climate.
3. Soi dogs
4. Trash
5. Noise, i.e., near constant barking dogs, neighbors yelling, chickens cackling, loud bikes and tuk tuks, advertising trucks blaring over loud speakers, advertising over loud speakers in stores, outdoor music venues being so loud as to be heard for miles but too loud to listen to if at the event, etc.
6. Cost of things like new cars, cameras, gas, cheese, wine, etc.
7. Inability to conveniently shop for stuff on the internet.
8. Import duty, if you do find an internet site that will ship to Thailand.
9. Dishonest expats preying on other expats (I encountered this mainly in the real estate trade there).
10. Not feeling welcome or feeling like I belong there, i.e., immigration hoops to stay long term, inability to own property, dual pricing, etc.
11. Rats
12. Snakes
13. Dangerous highways
14. Having to go to a hospital (mostly) just to see a doctor for something minor.
15. Parking hassles in town
16. Not being able to buy decent clothes in a size that fits or a style that I want to wear.
17. Cost of playing golf
18. Caddies
19. Murkiness and general lack of safe sea waters to swim in.
20. Cost of property (rent or buy) in town
21. Motorbikes i.e., the shear number and the way they are driven against traffic, on sidewalks, weaving through traffic, speeding by cars between lanes or near the curb in slow traffic.
22. Corrupt cops
23. Lack of simple logic on the part of Thais
24. Cost of maintaining property, i.e., even though labor is cheap, quality is poor and maintenance is constant because of poor skills and the climate/Mother Nature trying to constantly reclaim her property.
25. Cost of travel to a location outside S.E. Asia
26. Quality of expat choice of friends, i.e., I found it hard to find good friends there with anything in common, maybe because Americans are in a huge minority of foreigners there, or maybe because I'm not a barfly and had to give up golf due to the cost.
27. Thai acquaintances asking for loans or help all the time.
28. The insane way the majority of people drive.
29. The lack of decent public transport in the city, i.e., no taxies except tuk tuks or Songteaws.
30. Potholed or unpaved roads in and around the city.
31. Not being able to own a firearm
32. Having to do extra reporting every year to the U.S. treasury (outside of normal tax filing), i.e. FBAR Fincen stuff.
33. Shortages of municipal water
34. Having to have/maintain a water storage tank/home water pump because of low municipal water pressure.
35. Municipal water quality
36. Single room air conditioners
37. Lack of variety of climate and landscape throughout the country
38. Smokers, i.e., going to a nice restaurant only to have to breathe so much smoke that it affects the taste of your meal.
39. Narrow aisles in supermarkets
40. Restocking of shelves in those narrow aisles during peak shopping hours
41. Cost of western food items in stores, i.e., general high cost of places where I liked the imported selection (Villa Market). In contrast, the Asian market here where my wife can buy all the same stuff she cooked with in Thailand is just as cheap as the American market chains.
42. No Costco
43. No Walmart
43. No Walgreens (mainly for over the counter meds not available in Thailand)
44. No Trader Joes
45. Inconvenience, i.e., here I can literally get anything I want within ten minutes of where I live or over the internet without leaving my home. There I had to search the city, go to Bangkok, beg friends to bring things back from overseas with them, or beg friends/family to send things from the U.S.
46. Inability to sell real estate in a reasonable time frame.
Likes during my "ten year retirement" there or what I do miss:
1. The few good expat friends I did have there (mostly Canadian, English, and Swedish), sadly most of the Americans I liked there left after a short time. The ones who stayed long term (that I met) turned out to be a strange bunch.
2. Weekly lunches with my good friend Lars!
3. The genuine friendliness of most of the Thais I got to know there.
4. Good cheap eats, mainly street food and snacks
5. Chang beer (not the export stuff, but the high octane stuff)
6. Cost of building a premium quality home.
7. Bum guns!
8. Low cost of hand car washes
9. Low cost of a haircut
10. Lower cost of health care
11. Lower taxes
12. The privacy of a walled or high fenced/gated property, i.e., keeps solicitors (not lawyers but the American "solicitors" or door to door salesmen) from walking up to your door
13. Low cost of municipal water
14. Lower cost of auto maintenance
15. Lower cost of general labor
16. Good variety of reasonably priced restaurant food type choices in a relatively small area (Hua Hin)
