Itinerary Advice for 13 days in Portugal
 

I would love some feedback on the following itinerary:

DAY 1) ~ arrive in Porto late afternoon

DAYS 2,3,4) ~ in Porto

DAY 5) ~ head to Coimbra/ Conimbriga spend the night in Coimbra

Day 6) ~ to Lagos

Days 7,8,9) ~ in Lagos

Day 10) ~ to Lisbon

Days 11, 12, 13) ~ in Lisbon

Day 14) ~ depart Lisbon

FYI .... we will be using trains and buses to get from place to place which we are quite comfortable with. Thanks for your thoughts!
