We have 3 hours to kill before our kids arrive in Madrid. What activity would you suggest we can do in that time frame. We arrive at the airport 4 hours before our kids do and want to see a few sights in the mean time. Should we get a car or get a taxi? Also found out there are no trains to Rascafria (bus only). We could get a car but do we really need one to get around Rascafria? We only have a short time in Madrid on the 9th our flight out is 6pm. We thouhgt we would come int Madrid early so we can get a little time touring Madrid. What would you suggest on that last day. We should have about 6 hours before we have to be at the airport on the last day.
