Let renters book a boat for several days, with an optional discount.
Renters pick Multiple days as the length and choose a last day. Each day is priced at that day's full-day price (smart pricing included), with your multi-day discount taken off every day after the first.
Set the longest trip and the discount in Settings → Bookings & renter ID. Multi-day bookings block the boat for every day, show on your Google Calendar as one event, and the thank-you text goes out the day after the last day.
