My family will be vacationing 90 min from DC on Oct. 11th - Oct. 15th. We plan to visit DC on either Thursday, Friday or Saturday. I'm thinking Friday or Saturday. Which day is best based on crowds. I've also heard to be mindful of rush hour during the work week. I'm assuming we could lose quite a bit of time sitting in traffic on the tour bus?? We want to get the best bang for our buck in regards to time well spent to ensure we can see as much as we can in 1 day. We understand to get the full experience, we should look at another vacation to DC alone as it will require multiple days to get the best experience. Any suggestions? Looks like Thursday is 60% chance of rain...so not thrilled about that. Friday or Saturday is our only other options. Thank you for any suggestions that can be provided!
