"I booked this stay at Delphi with the intention of taking advantage of the activities for kids and ended up being really disappointed. If you are interested in the activities, make sure you book them WELL in advance. I tried to book a few days before our arrival and everything was unavailable. We tried to book when we arrived, thinking there might be a cancellation, but all of the courses were shut down. We were able to rent bikes and ride around, which was fun and the bike rental staff was very pleasant.
We tried to take advantage of the pool, but it is not available for children, or after 6 pm.
The dinner staff seemed really overwhelmed and the food was OK for the high price.
The location was beautiful and if you are planning an adult retreat that involved day activities and early bed, then this is a great spot."
