It is really necessary to reserve the bus ahead of time? I mean if we don't what are the chances we can get on the 3pm bus just by walking up and trying to buy tickets? Will it likely be sold out ahead of time? I ask b/c the bus website won't take my credit cards because i don't have any of that verified by visa crap. I ran into the same problem when i tried to buy train tickets in Peru last year.

So you recommend paying the 31E to get the bus to drop us off right at our hotel? I don't want to play the part of annoying American tourist (too late) but what are the chances that the people manning the bus depot will speak English on either the BCN side or the Andorra side for the return back to BCN on Sunday (we are heading back after spa time to spend our final night in the city)?
