Timetable Challenge: Guernsey to Barcelona the cheap way 🇬🇬➡️🇪🇸

Inspired by Scott from Planes, Trains, Everything; I decided to take on my own timetable challenge and save the thick end of £100 by taking two buses, a boat, a train and a plane to Barcelona instead of simply taking two flights via Gatwick. Did I make it though? And was it worth the extra travel hassle?
