Questions about debarkation time & luggage in Barcelona

[karenlovesparis]

I have a 2 part question. We are on the Epic in January and we sailaway at 7pm. We are in an apartment with 5 adults the days prior and I want to take full advantage of the time in Barcelona. We have to check out of our apartment at 11:00 am. What to do that day and what about luggage? Are there any lockers at the port? Can we check in luggage as early as noon and then continue to sight see?

 

We will be arriving back in Barcelona at 5 am. I'm booking airfare and wanted to make sure I had enough time to get to the airport. We can do early walkoff with luggage. Would an 11:30 am flight work? Would a 2:00 pm be better? The later flight is more expensive but might give better peace of mind.

No need to answer the second half of the questions about flights. I found the information in an older post.
