Nothing much to add to London Flyer's advice. Only thing is that at small fields the radio is often done in Spanish. I have a crib sheet in PDF format, PM me if you want it. Also, have a look at the charts and note the Spanis names for the VRPs. While they are called W/E/S/N etc, they often also have local names and local pilots tend to use those. Helps with situational awareness.
Am not overly familiar with the area around Reus, but the wine growing area of the Priorat (roughly W of Reus) is quite beautiful.
Enjoy!
