Reshikhola to Zuluk

Hi,

We have a trip planned from 22nd december 2018 to 25th December 2018 started from NJP -Reshikhola-Gangtok-Njp Returen.

We booked Reshi River cottage checked-in 22nd Dec and Check-out on 24th Dec, We want to visit Zuluk,Nathang Valley.

My questing: Can we visit Zuluk and return at Reshikhola ? or as we are going to Gangtok on 24th Dec then we will cover Zuluk on the way of Gangtok?
