We will be arriving prior to the Wonder TA at 6:45 a.m., too, in 9 weeks. Our plan is to check our luggage at the hotel (Hotel Jazz) and then scoot out to grab a nosh. Then a slow walk to La Sagrada Familia stopping off at any stores that pique our fancy. We have tickets for the 12:30 guided tour of LSF. Once finished we will make our way back towards the hotel. We will stop for an early dinner at the Obama Gastropub (close to Plaza de Catalunya, great prices AND they don't close for siesta times like many other restaurants do) before returning to the hotel for an early night. We have a Spain Day Tour the following day that will do Barcelona sights including Park Guell and Montserrat. Speaking of Park Guell, that would be a fantastic thing to do for you. It opens early, too.
