I have booked 2 days at Copper Creek and 2 days at SSR for August. I want to drop the 2 SSR days and book 2 at BLT (it's currently available online). When I tried to cancel SSR online it prompted me that if the reservation is linked that I need to call and make the cancellation by phone. How do I know if the reservations are linked? They have two different Travel Plan numbers online.
