We are excited to be gearing up for our trip in a couple weeks! We will be driving around Costa Brava (basing ourselves in Begur, and likely staying mostly in the region to the south of Pals since our time is limited)-- is a GPS rental necessary? We do plan to purchase a local SIM upon arriving in Barcelona, so were hoping that perhaps Google Maps would be enough -- if it is fairly accurate for driving directions in the area, and if data coverage is good enoug (with a paper map as backup). Is there a particular carrier/network we should go with that would be better in the area?
Many thanks in advance!
