Caveat: yes I know we should spend way more time in Sevilla, but this is what it is.
On Thursday May 19th my plan is to head for Seville and park in the morning at the Blas Infante parking lot on the west bank of the river.
Then walk east across the bridge to the Plaza de Espana, the Royal Alcazar, the Cathedral, and perhaps the Casa de Pilatos.
Then return in the later afternoon by walking (or taxi if exhausted/too hot/etc.) to the Blas Infante parking.
Does this sound like a pleasant journey or is it fraught with complications? Too ambitious?
