Advices about peak season in Lake Toba & North Sumatra are much appreciated.
I plan to go to North Sumatra from 31Jan2018 to 17Feb2018.
Is first week of Feb2018 considered shoulder or off peak season in Lake Toba? Would walk-in accommodation be a problem as do not intend to pre-book.
Route : Medan-Lake Toba-Brestagi-Bukit Lawang-Medan
Thank you in advance.
