Although the typical Venetian way of dining is to have a coffee and small pastry (a cornetto) in the morning ,many hotels offer a complete buffet breakfast in their rate. I typically stay in a 4 star hotel which offers juice, coffee, tea, cappuccino, pastries, fruit, eggs, sausages, cold meat and cheese from 7-10 AM. So, if one elects to eat a generous breakfast, then it is surely possible to skip lunch, have some ciccietti in the afternoon and opt for a nice dinner,.
