Interesting fact about Portugal is that concert tickets are not allowed to be sold for over face value. It is a crime, and the authorities recently charged several individuals for selling Coldplay concert tickets for above face value.
We booked our Roger Waters tickets for the Altice Arena when they were made available. We got the golden circle seats for 100 euros each. We will take the metro from our apartment to the Oriente station where the arena is right outside.
We just booked the NOS Alive 2023 festival for the opening day of July 6th. The Black Keys and Red Hot Chili Peppers will be playing that day. The festival is at the Algés Promenade. The tickets were 75 euros each. We will be taking the metro to Cais do Sodre and then grab the train to Algés.
