Is it easy to arrange taxis in the Leamington Spa area? Can you flag one or do you have to prebook? We are staying in Leamington Spa for three nights but want to go to Warwick Castle one day which is only 4 miles away. I have looked at the train and the bus schedules and it looks like we would still have to walk a mile to the actual castle after waiting around for transit, so I am thinking that a taxi would be more efficient (more costly too but there are four of us).
Question #2: Leamington Spa seems like a very nice place. Any favourite sights/restaurants etc?
