I have about 85,000 reward credits with CET. I often travel to Lake Tahoe since it is so close. When I was there last month I charged a few things to the room. I called down in the morning to see if a host could take those items off my bill. She said that she would have to use reward credits first and then could possibly start comping items. I think this policy varies throughout the CET network. Headed to Vegas on Monday and I'm thinking about using up all my reward credits because of this. I'm thinking of either converting them all to Hawaiian Airline miles or just spending them on some merchandise. Anyone else try and keep a 0 reward credits balance? Should I keep it at 0?
