Hello friends! I am cruising for the first time on RCI in April on the Symphony of the Seas, departing from Barcelona. I will get to the port by Airport Transfer around 11am. I would like to drop my checked bag at the ship, so that I can take the 3 or so hours just to do some quick sightseeing. Is this possible? (My check in is 3:30-4pm). I have tried looking around the net for answers but would love to know if any of you have had this experience. Thank you!
