Hi,
In La Coruña I highly recommend that you take the excursion to the stunning city of Santiago de Compostela (an hour from Coruña). Although the Cathedral here is what gets top billing, the historic town itself is beautiful. It is pretty much pedestrianized , full of medieval stone buildings, lovely to walk around. If you are adventuresome eating, stop for some "pulpo a la feria" , their signature dish (octopus). Yummy!
In Bilbao, I wouldn't miss the Guggenheim, frankly more for the building itself than its art collection. Cross the bridge over the river to the opposite side of town , and admire the building from there. On that side you also have the old town and market which is worth a look.
In Valencia we only had a few hours, so we walked around the town on our own and also visited their Central market, which is a beauty. IMO, it is up there with La BoquerÃa market in Barcelona.
Honfleur in itself is lovely, but if you have never been to Normandy and the D day beaches I would recommend a tour there (if they offer it). It is very emotional and impressive.
