How would you spend one night in Bangkok?

Book a hotel in the Sukhumvit area (S15 hotel is fairly new and great staff and 2 minute walk to Skytrain). Take Skytrain to Siam Paragon shopping, eating, bowling and eating. Go to Patpong and walk around the night market for cheap goods. Back to Sukhumvit and visit the local night life areas. Get some sleep....To the Airport
