We were told to Taxi C - G cross Runway XX to the gate. We contacted ramp and were given taxi to the gate. Our gate was X2 and we made the mistake of picking the wrong alley and started down the odd gate side. We realized our mistake as well as Ramp Control and we asked to go up the next line over and then to the even numbered side gates. We apologized for this and Ramp was pleasant towards us; told us 'Oh you're good; don't worry' allowing us to turn. It was not a busy time on the ground and we had plenty of room to make our turns to get to our gate. There was no safety issue involved but I feel it to be the correct choice in filing this.Contributing factors: I had not touched an airplane in over 1 month and I had not flown as Captain in well over 1.5 months or been to ZZZ in over 2 months; so I was focusing and not splitting attention accordingly I would say. I had my charts open and just misread.We were delayed all day so there was a time pressure.The gate that I was going to next was on the odd numbered side and I think I was thinking of the odd side due to this.I had been sitting in a crash pad for a few days and I believe that the stress of commuting and not being home for over 6 days may have had a factor on my mental state.Things learned: Slow down and read the charts better as well as make sure to properly look at the gate information displayed on the ACARS. It is always OK to ask for help. Never assume one gate vs the other. Not actively working means focus more on the task at hand for degraded skills.
Air carrier pilot reported a ramp incursion and cited lack of flying as a contributing factor.
