jan_az, you are confirmed! Let's hope you can find a flight

I'll update the Web site with today's joinees later tonight.
Thanks for the tip on the hotel SeeYa, that's a difference of 40EUR for the weekend and just about enough to buy a round of drinks!
And finally, Fred. Good info. Those buses are nice - big and comfortable, your luggage goes underneath (just like Greyhound!). The instructions to arrive at the hotel from the bus stop take longer to read than it does to get there.
One quick note on flights: BCN is served by a bunch of LCCs so if you can't get an award or cheap flight directly here then LON (EasyJet), CDG (Vueling.com), BRU (Vueling.com), and AMS (BasiqAir) are all good options, as is MAD (with the UX or IB shuttle).
I've got a feeling this is going to be a great weekend.
