How much does accomodation, food, bus travel etc. cost in thailand? Is phuket also safe?

I dont know about the South but i live in Bangkok so here in Bangkok it depends like what kind of hotel do u wanna stay in. t ranges from 300 baht + . If you eat from street stalls then it costs you around 30 baht plus. Bus travel is around 300 baht plus. Well I think Phuket must be pretty much safe because i never heard any dangereous activities happening in Pukhet.
