Family Vacation Ideas (help!) - East Coast Summer 2027

Hello! My extended family vacations together every other year and it's almost time to present ideas for next year. We are a pretty large group and I feel like I am struggling with finding a location that fits everyone's needs. Previously we have been to Ocean Isle (NC), Orlando (FL), and the Badlands (SD). Would anyone have any suggestions? Here are the guidelines I am trying to follow:

• Within 8 or 9 hour driving distance from Greensboro, NC
• Most of the family lives in NC and we have done beaches a lot, always open to another beach year but am trying to think outside the box!
• Budget to mid level price range (Previously spent $1,200 per family to go in on AirBnBs)
• 18 people - Family 1 (2 adults), Family 2 (2 adults), Family 3 (2 adults but would ideally want two separate bedrooms), Family 4 (2 adults and 2 kids), Family 5 (2 adults and 2 kids), Family 6 (2 adults and 2 kids), Family 7 (2 adults) - So if we did an AirBnb we would ideally need 8 or 9 bedrooms!
• Most of the kids are elementary aged, one toddler (age 3) and one baby (1 yr)
• I am tempted to do a hotel or rentals in the same condo unit since the family is getting so large so that's an option as well!

Thank you in advance for suggestions I am really struggling!!
