I'm looking at several of the Funtime Certificates such as Orlando (CORLANDO), Las Vegas (CVEGAS) and Bahamas Cruise & Resort Vacation (CCS). There are several hotels/resorts listed on each. Is the customer able to select which resort they prefer (1st choice, 2nd choice) or is the resort just assigned to them based on availability? There are several hotels/resorts listed - some would be a much better deal than others. (Some are $45 per night on Travelocity while others are $139 per night.) Thanks!
