We like using Hop On Hop Off and CitySightseeing Sevilla has some surprise walking tours that were part of the ticket price. The walking tours are ’free’ if you buy tricket . I guess you could say they were included in the price. The one day ticket is sufficient for Sevilla. We did 2 walking tours and the loop. Our Guide, Alex, spoke Spanish and English, so everyone was included. He was very knowledgeable and a good sense of humour He set a cracking pace so a little steadier would be best. A great day out.
