Spending an extra day in Athens on my Southbound trip next Spring and I really want to make it out to Delphi. I have read that this gentleman is a great way to do it:

Does anyone here have any experience using the Spiros service? I checked and he is free the day I would need -- a bit pricey for a solo traveler, but if he's the best I would pop for it.
Also is adding Thermopylae worth it? Seems interesting if not essential and a good way to round out the day.
