I would like to travel to Newport in early October and stay at the Attwater hotel. Is it best to travel by plane or train. I researched Kingston, RI Amtrak station vs. Green airport and I am not sure which is best and how I will get from the airport or station to the hotel. I won't have a rental car. Also is Attwater near major sites: mansions, shops, museums, etc.
Thank you in advance for your help.
