For those who have more time, consider adding day trips to Montserrat from Barcelona, Sintra from Lisbon, or Santiago de Compostela from Porto. For those who have less time, you may opt to either skip Porto or Madrid to allocate more days in other cities. Also, be aware that some attractions may require advanced booking, especially during peak season.
