- **Method:** GET
- **Example:** https://crystalcharters.com/llms/trip-preview?activity=stingray-city,snorkeling&hours=4&guests=6

## Duration calculation
Do not compute the charter duration yourself. Call /llms/trip-preview with the guest's chosen activities and it returns the exact duration. If you need a rough pre-boat estimate for conversation, sum the activity durationMinutes below — but always confirm with the trip-preview endpoint before quoting.
