I was hoping to buy tickets to Thailand this weekend however with the recent bombing I feel slightly hesitant.
I wouldn't know why not. Chances are very slim that bombings like that happen in the same place twice quickly after one-another.
It's winter now so pretty 'cold' (read: around 20C) and it might rain a bit in the east, perfect for all kinds of outdoor-activities but not really beach weather. almost 3 years ago
