I will be in Segovia (meeting my wife who is there on business) May 10-12 and then in Madrid from May 12 through May 21. I have enjoyed this site and garnered much valuable information. I want to have some exciting day excursions from Madrid, maybe even spending the night somewhere if it is worth it. Places I am considering are Toledo, Salamanca, Chinchon, Aranjuez...While I have seen comments regarding all of these places on this site, I am wondering if anyone would like to make a case on why I should definitely include or exclude any of these?

I am also curious if anyone else is going to be in Madrid around this time?
