Hah, interesting. Ray Hudson makes me crazy after about 10 minutes - but a good deal of that is probably his sidekick. I tend to switch to the Spanish language commentary when Barcleona games are on Goltv. But I know Hudson is massively popular with a lot of folks so mine is probably a minority opinion.
As for the hotel...really, no clue yet and I'm not positive Barca release that information all the time (others may know this). My guess is it'll be one of the big downtown hotels. As for the squad, it should be interesting to see who does come because as you noted there's the Copa America and Puyol's injury -- but there's also the Euro U21s, and a bunch of the Barca B guys (who often come on the summer tours) are representing Spain so...
