This might have been covered before, but I was hoping for some guidance. We were hoping to see one of the performances at the Palau de la Musica Catalana in Barcelona in early July. As someone who packs really light (carry-on only), I'm concerned about making sure I have appropriate clothes for the concert. If it matters, we'll be sitting in the cheap seats.
One of us is very uncomfortable in the heat. And we all know how hot it can get in July. So, can we wear dark jeans and a polo-type shirt (we're both men)? Is a jacket required? How about short pants?
Any advice is appreciated. Although we've traveled to Spain annually for the last 12 years, we've never been to the Palau.
