🧳 游客 = 游 (travel/swim) + 客 (guest) — a traveling guest, i.e. tourist
游 carries the sense of roaming or drifting (originally swimming), and 客 means guest or visitor. Together: someone visiting away from home — a tourist. The same 客 appears in 顾客 (customer) and 乘客 (passenger).
游 — water radical 氵 + 斿 (banner/streamer)
游 combines the water radical 氵 with 斿, which depicts a banner streaming in the wind. The original sense was a flag fluttering or floating, extended to drifting on water, swimming, and wandering. Today it commonly means to swim, travel, or roam.
