In my early days in BKK I booked a trip to Samui starting from my hotel. After being picked up in a mini bus I was surprised half an hour later when the five of us were transferred to a pick up truck. After another 45 minutes I noticed we were passing the hotel I’d been staying at. Don’t book trips at your hotel. Find out where the bus leaves from and buy a ticket there. For Hua Hin it will probably be the Northern bus terminal near Pinklao, or the bus from the airport.
Estimated cost please. 😊 I have a purifying system in Chiang Mai and I agree it’s much, much more convenient. However the system cost 6,500 baht and filters need replacing every 12 months or so for 1000baht +. There’s just no way it is cheaper even ‘in the long run’ than refilling at a shared station or having bottled water delivered.
I have a filter system, and I’d love to see your numbers showing how having one can work out cheaper than bottled water in Thailand. 😊 The most cost effective solution is using filling stations as mentioned. The problem is that it’s inconvenient.
