Went camping in Spain in 1992. Both sea-sick, the tent broke after 4 days, Brittany Ferries wouldn't let us take an earlier ferry back, hired a tent which got flooded, ended up staying in a sequence of cheap hotels and B&Bs (one owned by a miserable old cow with a portrait of Franco on the wall and wouldn't let us use her cooker), got sunstroke and my feet sunburnt, food poisoning from a Pizza takeaway in Santander and I couldn't speak a word of the language.
Apart from that, it was great.
