This tour is a great mix of partying and sightseeing! The weather's almost guaranteed to be good and you see a large area in a week.
Iberian Adventure by Busabout was an experience of a lifetime and i highly recommend it to anyone. Even though you travel with a group, you can do everything independently and you have the freedom to do whatever you want in the towns you visit, however the Guide was excellent and made the experience all that more amazing and showed us how to live like a local and experience the culture to the fullest.
