OK, so it looks like this is where we are right now:

Day 0 Drive to Cumberland, stay at the Holiday Inn
Day 1 Cumberland to Little Orleans 43.7 miles, stay at the Little Orleans Lodge
Day 2 Little Orleans to Williamsport 41.4 miles, stay at the Red Roof Inn
Day 3 Williamsport to Harpers Ferry 38.7 miles, stay at the Comfort Inn
Day 4 Harpers Ferry to Leesburg, 25.2 miles, stay at the Best Western
Day 5 Leesburg to Georgetown 35.5 miles, metro home and stay our own beds

Since we're talking 6 days now, should we start on a Sunday and end on a Friday, or start on a Monday and end on a Saturday, so we have the weekend to get back to our normal routines? Or start on Tuesday, October 7 (just a couple of days after the Seagull) and end on Sunday, October 12, with Columbus Day as our recovery day?

Velobambina, I don't know about the dog-friendliness of the hotels, but you can check it out. They're all on the list at the bottom of this page.
