Good video but missing: (1) How to go to Hua Hin from BKK, air, train, taxi,…. (2) How to go around Hua Hin tuk tuk, bus, songtheo,… (3) How to go to National Parks. Mainly you had the “what” but you need the “how”.
The best way to get from hua hin is by taxi for now , however thery are building a high speed train line direct from bkk which is nearing completion. Make the effort to visit, it is very worth while
