I've never been outside of the Bangkok Airport and this might be my first chance to see the city. At the moment, my fiancee and I have a room reserved at the Renaissance Bangkok Ratchaprasong. Is it worth our time to go into the city for such a quick trip? We want to get some authentic Thai food and had our hearts set on trying those crazy foot massages, but I also don't know if the spas run all night. I arrive at 7:30pm on May 21st and leave at 7:40am the following morning. One thing to note is that we're also flying Business and it's my first time traveling through here in J. I hear there's some good stuff to experience in the airport if we decided to stay there instead. Do business class passengers also get free massages like first class travelers? And are there beds or private rooms in the business lounges? Thanks in advance for any suggestions or words of wisdom.
