No dedicated DL like with RC. There is a dedicated lounge for suite guest. Retreat Lounge/ Michaels Club. CC HH in the evening (except for the first evening, nothing) from 5 to 7:PM is at most bars and the drinks are from the CC HH beverage menu. Unlimited drinks during that time frame. Like with RCs CAS you will receive in your stateroom a detailed list of Celebrity CC perks/benefits for your cruise.
A huge plus for Celebrity is no inside smoking including the casino. Unless you're a smoker than that may not be a huge plus.
