Hotel Pan in Delphi was where I was directed by a Trip Advisor DE who actually lives in Delphi ... We were very pleased. It's just 100 yards or so from the Bus stop, on the downhill side of the main street. In May '11 I paid I think €30 for single rate. The owner asked, is this main floor OK? Uh, I said doubtfully, let's see the rooms first. We walked back on a corridor, into a room, onto its balcony and --- hawks were circling BELOW us!!! The view was straight down the mountainside, to an olive-grove plain, to the sea. No problem! The rate included Continental breakfast at the early time we requested (7 AM), so we could stroll leisurely to the ruins site to enter at 8. When we had checked in at 4:30 PM, our hotelier also had tipped us off to the best sequence (which may not be available to you in April). He advised going first to the Museum, right then, because it was open until 7, and would be virtually empty ... and then to go to the site first thing in the AM, since the bus tours arrive about 10. Excellent advice.
