Bang goes your buck
While a developing capital, I found Bangkok to be charmless and poorly maintained and organised compared to smaller Asian capitals. For every 2 Thai touts trying to rip you off there is at least one honest Thai that will help you wether you ask or not. Get out of Bangkok go to Aytthaya and see the temples there, only slightly cheaper (with train tickets) than Bangkok temples
Insider Tip:Stay near Hua lumphong or the more tourist koh San road/ grand palace area. Further afield can be hard to get to these key tourist areas given that the grand palace is 500 baht alone, you'll want out your travel costs.
