Its not thoughtless to stay in a hotel - its not their fault they were poisoned.
If it was the UK there would (usually) be a vigorous police investigation if 6 Japanese tourists and some English staff died in Southampton Holiday Inn. Thailand it gets suppressed. I believe we can apply our standards to a country that actively advertises itself and promotes itself as a great place for Westerners to come holiday. If it is not a safe place then our governments should advise us not to travel there, or at least that Thailand has poor health and safety and to beware its hotels and guesthouses. These people are pefrectly to entitled therefore to set uip this website to warn people HTH.
BTW Thailand receives 3 times more men as tourists than women, which the authorities have put down to their amazing golf courses HTH.
