Thanks Gwilty & Aceman. Its on my shortlist for Jan 2018. I don't know too much about it, other than its the right time of year for the South West, so I guess we'd do the standard loop into the hills to Kandy, Sigiriya, the ancient cities, tea country, World's End and down to the southern beaches & back up the West coast.
Our daughter will be 13 by then & a fairly seasoned traveller, so I hope she'd enjoy it - I think she'd like the elephants & beaches. Did you go whale watching from Mirissa? How did you organise the driver?
