Inadvertently taxied through 'taxiway island'.  While taxiing in toward gate; we taxied through the south 'island/no taxi' area between taxiways J3 & J4. It was late night; and I had turned off taxi light as courtesy to opposite direction aircraft on taxiway J; and marshallers in gate area. When I turned toward gate; I proceed through the UNLIT 'no taxi' area. As we passed by BLACK vertical marker the FO (First Officer) noticed we had taxied through the 'no taxi' island. If airports feel it's important enough to mark an area unavailable for aircraft movement during daylight hours; maybe it would be wise to illuminate it during hour of darkness.
Taxiing into gate in MCO we were cleared to enter the ramp on J3. As we turned into J3 we proceeded into our gate. After shutdown we realized we may have taxied through the edge of the south most green panted area between J3 and J4. This area does not have any lighting.
Air carrier flight crew reported inadvertently taxiing through a 'no taxi' area at MCO; noting that the area is not lit at night.
