I also disembark in Barcelona. Afterwards will spend about a week between Paris and the UK before flying home. Happy with those plans, but....
Just now imagining what could have been a more extended holiday by reboarding Serenade in Southampton for a B2B of Ultimate Denmark, Germany & Sweden + Norweigian Fjords. Could have used those 16 days between Barcelona and Southampton to independently travel to Paris and the UK. But like you, too late to make changes - my flight home is already booked. Oh well, still happy with the four mini segments I've booked. 😀
