People can either ride down Thursday night, or Friday morning/night depending on work & schedules.
Departure would be at checkout on Sunday (assume 10-11 AM).
Rough assumptions:
Lodging: (If 6 people @ a house (VRBO, airbnb, etc) $120 per person, per night (each want a bed - can change)
Food: Group breakfast & dinner Friday & Saturday = $15 per person, per meal = $60. All lunch/snacks on your own & as needed while riding.
Miles Ridden: 300 +/- there, 150 +/- per day, 300 +/- return = 900 +/- total miles. 30 gallons of gas @ $3.50/gal = $105 in gas
Lots more to figure out as we narrow dates & attendees. Just wanted to get a starting point out there.
