My family will be traveling to Barcelona and vicinity for 14 days in mid June (includes 2 travel days). I need help rounding out the last few days of my trip. We'll have 4 full days in Barcelona, and then we'll be in the Costa Brava region for 5 full days. We'll meet up with friends and rent a car in Girona. We have plans to explore the area and with Girona, Tossa de Mar, and Montserrat on the list. (Yes, I do realize that Montserrat might be easier to get to from Barcelona, but we want to go with our friends.)
What I am struggling with is the last 3 days... We will part ways with our friends and would like a quiet last couple of days to just relax and take in the area/culture before flying out of BCN. We will have a car and want to be settle near a beach with restaurants/town within walking distance. Do you recommend Llefranc, or should we turn in the car in Girona and take the train south of Barcelona, staying somewhere like Calafell? Is it better to stay in the Costa Brava region? I am wondering how packed Llefranc gets late June and whether Calafell would be more relaxing with less people.
