I usually stay in the high floors or penthouses of hotels. One of the bizarre aspects I love about this is looking down on rooftops. You see things not intended to be seen by the general public, It’s sort of like a private museum tour.
Take a different view of your client’s operation. I used to visit the warehouses, talk to secretaries at lunch, and take the stairs instead of the elevators. Your private tour will enable you to offer distinct insights to your buyer. (I found card games in the warehouses, romantic encounters in the stairwells, and received more accurate information from the secretaries than from the executive team).
