Hmm, the weather is not so stable, but they still want to experience something? After all, we have an idea.
They take the ship from Weggis to Brunnen just before 10am or 11am. Stroll along the lake, past the Nessi playground to the child-friendly restaurant Viktoria, where they treat themselves to a fine lunch (Italian menu).
Return to Weggis by boat, or for a change by bus, which goes via Vitznau to Weggis.
