5 Nights in Bangkok

Howdy, people. I am preparing a trip to Bangkok in Thailand. I will probably stay there for 5 nights, not more. I would like to hear some of your suggestions how I could spend my time there. All your advices will be more than welcomed and very appreciated. Thanks in advance.

Hello to you too. I was last month in Bangkok for 5 nights and I had a great time. I stayed at Hotel Cafeteria. It has three stars. On the 2nd day I went to Floating market. After that I went to see River Kwai and the famous bridge. On the next day, you can go to see Sapphire Mine in Kanchanaburi. You should also make a tour down the Chao Phraya River on the following days. If I recall of something else, I will let you know. Have a great time in Bangkok. Safe trip!
