A week in Yellowstone / Bozeman for eight people works out around $18,179 before flights — $742 a night for a place sleeping four, scaled for the group, plus $75 per adult per day for food. From Denver, Los Angeles, Seattle it is cheaper for a family of four to drive than to fly.
Lodging and food only. Seven nights, whole-property rental, all fees in.
| Group | Lodging | Food | Total | Per person |
|---|---|---|---|---|
| 4 people | $5,194 | $2,100 | $7,294 | $1,824 |
| 8 people | $13,979 | $4,200 | $18,179 | $2,272 |
| 12 people | $19,117 | $6,300 | $25,417 | $2,118 |
Note the per-person column does not simply fall. A place sleeping four is the efficient unit; going to eight means changing property class, which costs more than double. Past eight it improves again — each additional person adds roughly half what they did over the first jump. The expensive step is condo to house, not the people you put in it.
Yellowstone / Bozeman is dearest in June and cheapest in January — a 76% swing on the same property.
