We're going to Seville and taking a number of day trips. I want to do a winery tour in Jerez, and I also want to go to Cadiz. While i don't want to rush a 2-hr-each-way trip to Cadiz, I also don't know if going to the winery tour at 1PM (the earliest we could reasonably get there given our sleep schedules and personalities) and then to Cadiz after the tour would be cramming too much into one day.
On the other hand, I don't know if there will be enough to do in Jerez just with the winery tour (we're not interested in horses!) and will be close to satiation point with cathedrals etc. from our time in Seville. Any points of view most welcome!
