I intend to spend 4 days and 5 nights at Huangshan. Is it sufficient? From Tunxi, there is tourist bus to Hongcun but how many hours is the bus ride? and how much does it cost? Is it possible to go to Hongcun in just one day - that means, we leave tunxi early in the morning for Hongcun and then come back to Tungxi at night?

Or is it possible for us to go to Hongcun, then stay one night at Hongcun, then go to Huangshan mountain without going back to Tunxi?
