My Husband and I are planning a 9 day trip to portugal in late June. I am trying to figure out where to go and spend our time. Thinking of doing 2-3 days in lisbon (with a day trip to Sintra in here) a few days in Caiscas and then possibly lagos (not sure if we should do this). Wasnt sure if it made much sense to go to Porto. What are peoples thoughts? We are 30 and have a modest budget, also would prefer to take public transportation around!
