Tips and ideas for Madrid & Lisbon please?

Madrid

Over the last year, although I was away a lot; it was for work. It meant I have a lot of holidays left over to use. So I’m making the most of the holidays and heading to Portugal again (twice in 2 years, Lagos and Madeira); this time Madrid and Lisbon. I want to soak up the freedom to wonder around Europe before Britain cuts ties with Europe. (I’m have plans for Scandinavia later in the year)

I’m pretty free and easy about everything but I’m planning to check out the amazing culture in both cities.┬á There is one solid thing I must do and thats visit the amazing rollercoaster parks in Madrid.

Any tips, suggestions and places I should stay are very welcomed…
