Hello!
My wife has to travel to Cannes for work, and we're looking at meeting up in San Sebastian. Neither of us have been, but have heard it's quite lovely. We're looking for a relaxing time, with good food & drink, and maybe a bit of adventure. From what I can tell, San Sebastian is well known for cuisine and beaches, which sounds great, but would spending 3-4 nights be too long? If not, what would you suggest to fill the time? Is a day trip to Bilbao worth it as a change of scenery? We're very open to recommendations on everything. Thank you!
