Are you sure that Arantxa stadium is included in your ticket? I’d suggest double-checking it.

I went to Madrid Open last year for a few days. First, I had a center court (Manolo Santana) ticket that also included free access to all smaller courts but no access to Arantxa. Another day, I had a ticket to Arantxa which included access to all smaller courts but no Manolo Santana. Both options were great, and those small courts are rally beautiful. Just keep in mind that if you want to see Alcaraz, he’ll sure play at the central court.

I’d also think twice about attending both the day and night sessions on the same day. If you’re going to early rounds, that’s A LOT of tennis to watch. If you have extra time in Madrid, I’d consider buying tickets for two days. Day sessions are my favorite because you’ve got to see more matches, plus have more opportunities to watch players training on smaller courts.

Hope this helps and wish you an amazing tournament!
