This was shared with me earlier today by one of my TA clients, who knew that I used to cruise solo on Carnival with frequency.
I'll skip my editorial of personal opinion.
110 Cruises - - NCL Platinum Plus / DCL Platinum / CCL Diminished Milestone/ RCI Platinum
Upcoming : 2017: Carnival Liberty (Halloween in Bahamas); Norwegian Epic #10 (Western); 2018: Norwegian Epic #11 (Eastern), Plus 4 more in 2018, and 1 in 2019
. . . . CCL: It is what it is.
