• I want to know the best places to visit in Bangkok!
• I want to go good sea

Hello Su Kyung!
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 is native Thai person and knows many good places that are not in travel books to visit, eat, and experience when you visit Bangkok. She can take you to many places that you can have fun and experience Thailand and she loves going to the sea!
Hotels in Bangkok are not expensive and they have many services to care for you.
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!
