Hi Cathy, many have asked this question on the board. I think that to be more comfortable you should either rent a car or take the train.
You can get great car deals on a Mercedes A Class which would be perfect for a family of 4, please see the rental car thread by clicking

I can not imagine that anyone would recommend a cab to Toledo with the overwhelming rip-offs discussed lately at the taxi rip-off thread
HERE
Renting a car would be the cheapest and best way to go, especially if you want to stop off and take pics. I can imagine a taxi driver with an ear to ear grin on his face just imagining all the Euros he will get you for if you tried that "stop here, stop here" on him, there goes your kids college funds
For RENFE (train) info, please see my
