How realistic is it to expect to accomplish the following: Arrive Barcelona by plane at 8:30 AM. Get through customs and deposit suitcases in locker. Catch Aerobus to Placa Catalunya by 10:00 AM for walking tour. At end of tour (11:30-12:00) get Aerobus back to airport from Placa Catalunya and retrieve bags in time to catch shuttle to next destination at 13:30.
Help and suggested modifications are appreciated! This 5 hour window is our only time in Barcelona, and we would hate to miss it entirely.
