I have JUST received an open invitation to stay in a friend's house in the outskirts of San Jose. I have never seriously considered a trip to CR, and don't have any sense of where to go or what to see. I don't think we could afford to go at all if we didn't have access to free accomodation. My question: is it worth going all the way to CR if we have to stay in San Jose? Can we do day trips or short overnight trips fron San Jose and get a good sense of wider CR? Is there enough for a familiy with young children (6 & 8) to enjoy in and around San Jose? Thanks posters for your help!!
