I will be travelling with 2 friends and I think a combination of light partying (dinner and bar, but no disco) and rest is preferred. Since it's a layover, we'll already be checked in so we'll just need to clear security at the airport in the morning. I figure that being there by 6 should be sufficient. Any inexpensive clean and well-situated hotels to recommend? How about airport-city transit? Are there trains or buses or is taxi the way to go?
