Yep... "worth the cost" and "peanuts" are the same thing

Perhaps you are confused, so I will take the liberty of defining each word for you
Peanuts
(Informal.) A very small amount of money;
Worth
good or important enough to justify
Therefore, worth implies that the trip was "good" enough to justify the hefty cost, and does not mean the trip cost "peanuts" (very little amount of money.)
