Probably depends on your outlook in life.
Cheap markets bore me to death. Jim Thompsons house is a complete contrast to the rest of what Bangkok has to offer.
Agree regards to Tuk Tuk, they will rip you off if given the chance. As said they kept stopping off at touristy shops but we never bought.
All they do is waste your time and money.
As well as usual Thai things to do, really enjoyed Jim Thompson's House and (cough) massage!!!
