Just how far IS the Omni William Penn from the Westin?

Just how far IS the Omni William Penn from the Westin?

This picture was taken from in front of Anthrocon 2006's overflow hotel, the Omni William Penn. The over-exposed building 2 blocks away is the Westin, our primary hotel.

The walk is slightly longer than from the Adam's Mark to The Holiday Inn, but not unreasonable, IMHO.
