I (W) have a tummy bug: half the night speaking to the Great White Trumpet, manage to block the hotel's washbasin. Don't even ask how. And we fly back to London today. Fortunately, the worst is over by hotel checkout time: hot and cold flushes but I'm travellable. Barely. It was classic food poisoning, and I fear the octupus-wrangler from two nights ago may be to blame. We have run out of our 4-day Metro pass so just get a cab: the Placa Jaume L is just up the hill and as a seat of local government always has lots of cabs. Sleep away the time until the flight with music courtesy of the trusty MuVo, and have an entirely forgettable flight on an Airbus A320 back to Heathrow. I'd been looking forward to flying the Airbus, but it really is a disappointment compared to the Boeings I'm used to. Even allowing for my fragile state, the plane flies rough: engine vibration all the time during flight - and the air conditioning is a sad joke. Even Heathrow's taxiways feel extra bumpy. Just like me.
