Hello Choi,
There are so many places to visit in Bangkok it is difficult to tell you. Depending on what you are interested in seeing there is a wide variety of cultural, shopping, eating and partying places to visit. My girlfriend can help you find the best places to see, shop, eat and relax at... she is native to Thailand (and very good shopper!).
Hotels in Bangkok are not expensive and they have many services to care for you, such as spa and yoga.
If you want more detailed information feel free to write me and we can talk about how to plan your visit here.
Good Luck and have fun when you visit!
Mitch
