I just signed and made initial payment (Midgett). My departure fee was higher, so I presume it’s based on the rental cost. However, the house is a good size, with bells and whistles, for 3 couples, and 4 grandchildren. I take this fee to indicate the additional cleaning and sanitizing associated with COVID.
In 2020, (also Midgett) I do not recall a departure fee, however, we had booked the home before the virus was even talked about.
