• I want to know the best places to visit in Bangkok!
• I want to shopping

Wow Cristina!!
You want to visit 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... but you should plan about a week to see all the places on your list.
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 - also she is very good shopper and can show you many good places.
Hotels in Bangkok are not expensive and they have many services to care of 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!
