Reply To: Can't get back to "cart/reservation" if browsing away from page

So I need a little direction so I do not spend a week trying to figure this out. I need to be able to retrieve half done reservations or canceled reservations. if someone accidentally navigates away from the booking process while it is loading the next step, I don’t want them to get frustrated and leave my site and us have to track them down for payment and what not. Please help me figure this out as it will be beneficial to your customers as well.

Thank you in advance.
