Ya i also just came back...rainy days and nights sigh...but luckily it comes and go....

I recently came back from 3D2N Hua Hin trip ... all by free N easy.
Here is my simple itinerary ...

Day 1
- Took the A1 Bus from Don Mueang to Mo Chit BTS
- Take Mo Chit BTS and stop at Victory Monument BTS.
- Go down and walk to near roundabout, will see some minivan and people shouting Hua Hin.
- Take the minivan (will move after full) and tell them Hua Hin stop.
- Stay near night market (either Cicada or Chatchai/Chatsila)
- I stayed at Tanawit Resort & Spa.
- Walking distance to night market

Day 2
- Take tuk-tuk/Songtaews to go around Santorini Park/Swiss Sheep Farm.
- Take the return way either by passing minivan or taxi to any night market.

Day 3
- Went to Hua Hin beach (walking distance of 800m).
- Went to Railway Station (also walking distance from my hotel).
- Take minivan back to Bangkok & BTS/taxi to airport.

If you search Top 10 Hua Hin attraction, some are not cover in my trip due to my interest are more into Santorini & Sheep Farm. The rest are just compliment due to my long stay. It can be day trip by hiring one-day taxi.

Hope this info help me in planning.
