How long will it take me to get as far as Woodbridge in one day? I will be traveling on a Friday. I want to travel the rest of the trip on Saturday.
I would allow 6 hours.
The Hampton is closer to the exit, and in a bit more convenient area. The Holiday Inn is about 5 minutes from the Hampton Inn. There are other hotels, but some while in the description mention Woodbridge, are not. There is also a large Renaissance hotel, also close to the GSP, but I personally have never heard much positive about the place.
Be sure to pay attention to the signage at the exit off the GSP. Not particularly difficult, but not as straight forward as it could be.
