Top-notch gay comedians and DJs entertain onboard. And Wentworth takes care of her girls: for those looking to shed a few pounds, there's "Sweet Sweat Bootcamp" made possible by Shawn Harkins of Dr. Phil's Weight Loss Race; or "Sweet Sparks," an onboard networking and empowerment series designed to help you help yourself.

Coming up in 2010: a Kenyan safari, with stops Nairobi first, including Daphne Sheldrick's Elephant Orphanage (you'll want to take one of the babies home with you), the Giraffe Center, and St. Lazarus Community School, where you'll donate school supplies, meet the students and hear about their lives. Then it's off to game drives in Amboseli and Masai Mara.

The deals are sweet right now too, and there's even 12 month payment plan (from $71 per person per month) with no hidden fees or interest.
