The honest answer is: it depends on your crew's confidence and what night you're talking about.
Anchor when you can, take a quay or marina berth when you need to. The Ionian is forgiving enough that you have real flexibility—it's not like the Aegean where you're chasing shelter or dealing with the Meltemi [1].
Early Season & Peak Times
If you arrive late in August, every popular berth in Fiskardo or Vathi fills by mid-afternoon. In that case, book a town quay or marina spot in advance—it saves you circling and arguing with your crew. After that, you've got breathing room. The distances between stops are short enough that you're never desperate for a berth [2].

Pros
Anchoring saves money and gives you scenic isolation on calm nights
Town quays & marinas offer water, power, and zero stress
Cons
Anchoring requires good holding, early arrival, and midnight wind management
Marinas are pricier but include showers, restaurants, and easier crew handovers [3]
When to Anchor vs. Book a Berth
Anchor on: calm, scenic stops (Paxos, Meganissi, peace-seeker anchorages around Lefkas) [4]
Take a quay or marina on: nights where you're tired, the crew is frazzled, or it's Friday and everything's chaos
Wind reality: Force 2–5 most days in the Ionian—you're choosing logistics, not between danger and comfort [1]
