Northern Italy and Ticino Switzerland in June/July

Emerging from lurkerdom in search of recent thoughts about northern Italy. Heading there with our family of 3 in late June/early July. Planned stops include:

Venice

Lake District of Italy and Switzerland: Lakes Como, Lugano, and Maggiore (leaning toward staying in Lugano for these days but open to suggestion)

Liguria: Italian Riviera, mainly Cinque Terre and Camogli

Milan

Any and all thoughts and suggestions are welcome! It's our first time in Italy, none of us speak Italian, we are not renting a car (trains only), and we don't eat beef or pork, should that color your suggestions.

Thank you all!
