I hope you don't think you must stay in ryokans when in Kyoto. There are many, many fine western-style hotels. I, for one, simply do not do ryokans anymore but have enjoyed many nights in Kyoto. The advantages are being much closer to the historical and cultural sites, the ability to walk to and from the hotel or return for a change of clothing or a nap and, truth be told, the more central location for day trips(!)

Among the better day trips from Kyoto are Nara, Hikone and Osaka, all of which require zero connections from Kyoto Station. Osaka is nice but rather a repeat of the big city that is Tokyo. If you are into the nightlife and dining scene, Osaka is probably a fine choice. I like quiet, history, great food and culture so I always stay in Kyoto or Nara.
