The Nasa Vegas Hotel in Bangkok is a budget hotel that I stayed in a few years back. To be honest I found the rooms to be quite good. It certainly shows its age, but the hotel is a pleasant place to stay. Whilst it wasn’t built when I was there (late 2005) and its still not done yet (late 2007) the new train that will go all the way out to the airport will have a station near this hotel which will make it even easier to utilise. At the time the one down side was the lack of internet facilities though this might have changed.
