I just checked and Copper Creek does have availability at that time via
DVC Rental Store's confirmed reservations. These are reservations already booked by someone else who cancelled, so they're just waiting to be transferred to another customer. I love these as there is no suspense about availability. You just have to pay (in full up front, with no refund, of course). Each major
DVC rental broker has a list of confirmed reservations on their website.
So many people have cancelled trips due to Covid lately that confirmed reservations in general (via
DVC Rental Store, David's, etc.) are currently a great way to book trips. I've gotten other "impossible" reservations that way, such as a Hilton Head studio for this July.
