I used to have an apartment just outside Torrevieja in Punta Prima, never took in a game but City usually go near there pre-season don’t they? San Pedro del Pinatar I think.
It will be even easier I imagine when they are relegated to the Smartbank. Capacity is about 35000 so plenty of seats. You can buy online two days before kick off ( ticket is electronic to your phone )or at the ticket offices on the day.
