These picks nail the all-inclusive mountain formula: Montecito Sequoia Lodge leans hardest into summer camp intensity (all meals, activities, counselors included), so pack your kids and step back. Grand Lodge on Peak 7 and the Stowe and Big Sky options swap that for self-catered cabin living with heavier resort infrastructure — pools, theaters, organized programs — letting families decompress between adventures. Pick based on your tolerance for structure: pure camp energy versus cabin flexibility with built-in backup entertainment.
