My FIL has injured his back and has to opt our of his previously scheduled shore excursion (too vigorous). All the other shore excursions are booked, so he can't join ours - except our TA says we can book the private vehicle shore excursion. This is in Bilbao, by the way. I am wondering how the guides are with the private vehicle excursions if anyone has any experience. What else should we know before booking that? I've got an email in to Spain Day Tours, but they don't have a full trip yet. We depart on Wednesday, so I hope we can wrap this up before we leave. Thanks!
