Barcelona. Long weekend late Feb

[Every day a journey]

Off there with the Mrs for my 50th and there seems like plenty to do. (have been to Barcelona before but for a Grand Prix so didn't see anything of the city!)

Found a driving experience on Get Your Guide that looks like fun ( https://www.getyourguide.com/barcelona-l45/40-minu... ) but an extra £1000 insurance for people that usually drive RHD seems stupid.

I've driven more on the continent in the last four years than I have in the UK!

Could be an option but any other real good tips for the city?
