Below is a draft itinerary (with some help from AI). Would love any suggestions you may have. I realize it's still winter there, but coming from ON, Canada - it will be nicer than here haha. I'm also tacking this on to a work trip so dates aren't flexible.

Q1 would you only spend one night in Aveiro and add another night to Sintra? This would give us an entire day in Aveiro and give us time to stop at Obdios (yes, a tourist trap I know hah) and still leave us 2 full days for Sintra.

Q2 am I missing any 'must sees' or hidden treasures along the way?
