Are there any specific tips for someone considering a trip to Bali from the US? What is the best month for travel to Ubud? Which is best, to see Ubud or Sayan? How far is it between the two areas? About how many days is suggested to see two or three areas of the country? What are the best modes of travel around in and around Bali? It is a 30 hour flight from the USA, so I know I want to stay at least 10 days.
