i am also a single woman 34 (interesting to see there are quite a number of independent women in their 30s around). anyway, i will choose Princess over Carnival. Princess is more upscale, the age group is all ages. there are many middle class single men or women in their 30s and 40s in this cruise line, also Princess is popular with a lot of professional gays and lesbians who are well behaved and cool. Most staff of Princess are British, Canadian or Australian. They treat their customers more professionally.
I am going with Caribbean Princess (newest ship) to South Carib for 7 nights on 10/23/04. very good price from www.travelocity.com
. can be less than Carnival.
