My multigenerational hotel in Porto, Canto de Luz, was designed so grandparents, parents and kids share one roof without the bathroom queue, the noise wars, or the layout compromises that ruin a holiday. Adjoining family suites, elevator access throughout, wheelchair-friendly accessible rooms, a heated pool open every day of the year, and a daily homemade breakfast included in every rate. Three generations at the same table the morning after they arrive, nobody having to be the polite one.
