I am planning a trip this summer in Portugal with my wife and my 3 sons, ages 21, 19, and 17. We are starting in Porto and ending in the Algarve. We are making our way from Porto to Lisbon via car and wanted to split up the trip...opting to stay in Coimbra for a night. I know the Quinta das Lagrimas is a wonderful hotel, but not really geared towards family. Could someone please recommend some place nice that would be suitable for a family of 5. Thank you very much.
