For my 45th birthday present to myself, I want to take my kids (10 and 12) to Portugal. I am a single mom so probably traveling as a threesome. It is possible my brother and his family will join us, but I want this to be my trip. His budget is much greater than mine. I would love to develop a great itinerary. We would be there the last week in March and could possibly tack on a day or two on either end of that week so maybe 10 days total. Please help me develop this itinerary. I have read all the past posts and I am overwhelmed.
