only if you're a complete pansy. thailand is super safe if you're not a dumbass. it's far more dangerous as a tourist because you don't understand the country as much and you're more likely to be overcharged. also bangkok is better than hua hin for longer term stays. there's so much to do in bangkok. hua hin there isn't much at all to do but relax. chiang mai would be my next choice after (or even before) bangkok.
Thailand is perfectly safe, especially Phuket/Pattong.
I've walked alone on the streets of Pattong at like 3AM plenty of times and nothing has happened.
I am going for my 3rd time in Thailand in the beginning of April for about 10 to 15 days
