Sounds like a good opportunity but with 2 days mandatory in Bilbao every month you might as well limit it to Spain and Portugal only.
Or do you have teammates who are flying in every month from Africa/Middle east/Central Europe?

If I may ask do you pay for the travel or do you get reimbursed by your employer?
And even assuming 1 full travel day on either side, 4 days a month is a LOT less than 1/4.
