To facilitate easier booking of our champagne cruises we've added an on-line diary using Google calendars. The calendar shows busy where we have bookings. Our Champagne cruises usually run from 10am to 1pm for the morning session or from 2pm to 5pm in the afternoon. We've added 30 minutes either side of the charter on the Calendar to give us time to get ready, and clean up respectively. The event in the calendar only shows the start of the trip time, so it's just a matter of clicking on the event to get all the details.
We do other trips as well so sometimes it may be an all day event. Again, just click on the event to get the full picture.
