We just got back from Brassard. Aftercare costs are all included in that total price, unless something special comes up (like staying an extra day?). We paid absolutely nothing more except travel/preparation costs for me (the wife) - the package does include a night or two in a B&B beforehand and travel to and from the hospital from the airport/train station for the patient. Incidentally, the aftercare was fantastic; a minimum of 2 nurses on duty 24 hours a day, meals provided, laundry service, and regular checks from the doctor including on the day of discharge. It was hard to imagine someone being discharged 2-4 days postop, looking at the people in the residence at that point! Plus the convalescent residence and grounds are gorgeous.
He also required a $2000 deposit within 21 days of receiving a confirmation letter to guarantee the date and then a $2500 deposit 8 weeks before, with the balance due a month before. The confirmation letter arrived in late February when she'd requested to reserve the date in November, though, so there's some time before they actually expect any money.
