Were you looking to book a
Disney cruise? They can't be booked with UR since anything Disney is blocked. For other cruise lines, you would get 1.25 redemption with the CSP on the same price as booking direct. ($1000 cruise will cost 80k points) If you upgrade to a CSR after a year, you can get 1.5 redemption ($1000 cruise will cost 66.7k points). Right now due to the pandemic, you can also redeem at those same rates for groceries, restaurants, and home improvement stores. I believe that's through 9/30/20, but maybe it will get extended.
I'd argue redeeming for groceries etc is a better deal since I can usually get a better price or perks with a TA for cruises. Definitely not as satisfying as free travel though.
