Hotel booking range

Check-in / check-out with nightly prices under each day, booked nights that ranges can't cross, a 2-night minimum and a live total.

What's going on​

  • markedDates puts the price under each day and marks booked days disabled. Range selection never crosses a disabled day: tapping past one starts a new range.
  • minRangeDays ignores a check-out tap that's too close to check-in.
  • dayHeight={50} leaves room for the label.
  • Prices are summed per night with addDays, which is DST-safe.

As a sheet​

On phones, open the calendar from a summary bar. The confirm button (Done, or OK in Material) stays disabled until both dates are chosen, and in Material the headline above the calendar shows the range as it's picked:

<DatePickerSheet
  visible={open}
  onClose={() => setOpen(false)}
  title="Select dates"
  confirmLabel="Save dates"
  mode="range"
  value={range}
  onConfirm={setRange}
  minDate={today}
  minRangeDays={MIN_NIGHTS}
  markedDates={marks}
  dayHeight={50}
  sheetProps={{ height: 0.75 }}
/>
