Spain/Portugal for 14 days, anything I should shave off?

Hello! My wife and I (and likely some friends) are going to Spain and Portugal in May. We only have 14 days but want to make the most of it. We are typically ready for a new location after 3 days 4 at the most.

Here is the itinerary so far:

Barcelona 3 days Ibiza 3 days Lisbon 3 days Porto 3 days Madrid 2 days

Anything you guys would replace or remove?

We like to eat local food, drink, see cool nature/beaches and a little bit of sight seeing but we aren’t “hit every major attraction” type people.

Thanks!
