Anthony:
The area is probably more of a zoo than you remember!!
Exton to Villanova at 7:30 AM is easily 45 minutes if you go straight out Rt. 30 east. Shortest route but LOTS of lights and traffic. The alternative is Rt. 202 north, I-76 east then I-476 south. This however can be a disaster at 7:30AM. At 9:30AM, that route is better and I would use it at that time of day.
A another possible is Rt. 100 north to the PA turnpike, head east to the Valley Forge exit, I-76 east toward Philla then I-476 south to the Rt. 30 intersection. The turnpike is a breeze, I-76 and I-476 most likely won't be at 7:30 AM, by 9:30 AM most of the traffic will have moved out and it won't be bad.
There are a number of back roads that you could use. directions are more complicated.
Reading is a decent hike from Exton. I would probably take Rt. 100 north to the PA Turnpike, follow that west to I-176 north into Reading. Should be able to do that in less than an hour.
My office is in Exton, so if you need some local info, drop me an e-mail.
