We had booked the 8.45 am in-depth tour at Fallingwater. Despite the fact that the tour by George only gives 8.00 am as the earliest time, he was more than happy to pick us up at 6.30 am. He was highly informative about the history of the route to Fallingwater and about Fallingwater itself, which was a nice appetizer for the in-depth tour at the house. George was also very friendly and helpful generally. I would highly recommend him as your guide.
