Around the weekend, disturb one's rest to make journeys (5)

I believe the answer is:
treks
'journeys' is the definition.
(trek is a kind of journey)
'around the weekend disturb one's rest' is the wordplay.
'around' shows that the letters should be reversed in order.
'the weekend' becomes 'k' (I've seen this in other clues).
'disturb' means one lot of letters goes inside another (inserted letters disrupt or disturb the word).
'one's rest' becomes 'sert' (I am not sure about this - if you are sure you should believe this answer much more).
'k' going inside 'sert' is 'skert'.
'skert' reversed gives 'TREKS'.
'to make' is the link.
Can you help me to learn more?
(Another definition for treks that I've seen is " migrations".)
