Hi Blossom,
Yeah, Chatuchak can be quite hot and stuffy. My Thai friend hates that place

Its supposed to be huge, with a wide range of items from clothes, to furniture, artwork, antiques, to knick knacks and even pets! Like a huge flea market. It really depends on what you want to buy. The market has a website ... u can use it to check out whether they have things tt will be of interest to you.
Hehe...it'll be tough squeezing in sightseeing plus shopping. imagine me and my hubby can spend 4D/3N there just shopping alone. When we go to BKK, we nvr sightsee. well, we're not interested also lah..so easier

Lucky thing for us is that our interests are v similar..so we wun hafta worry tt one person wants to do something tt the other one doesn't.
Eh..Pathumwan isn't that much more expensive, and I hear its a nicer hotel too. Thought it was even more ex than Novotel Siam Sq (which is already more ex than Arnoma)
Well, hope u guys can work something out. PLan a schedule lor..like 1/2 day sightseeing...1/2 day shopping etc.
