We are planning on flying in from Seville to Lisbon and have 6 nights before we head back to the states. We want to have our Portugal time include Lisbon city, Beaches and Sintra. Would you recommend doing 3 nights in Lisbon and 3 nights somewhere relatively close and easy to get to like Cascais where we can get our beach fix? Or should we plant ourselves in Lisbon for all 6 nights and do day trips? We will be traveling with a toddler and will be renting houses/apartments.
Thank you!
