Just thought I'd let you know that vacations to go (discount site for cruises) is now offering singles cruises--and their cruises are on other lines besides Carnival. I'm glad to see another resource for us solo cruisers.
That's great to have more choices for singles to get together on cruises. I looked at the first 4 cruises designated for single's group travel and it seems their shared-cabin prices are in line with the competition when you include the port charges that are included elsewhere. However, according to my calculations, their cabin-to-yourself price seems to be $200 higher than some of the current single's cruise agencies. I prefer a cabin to myself and unless they offer a desired cruise that I can't get at one of those agencies, that higher cabin-to-myself price needs to be more competitive. I already have several cruises booked at these other agencies and I'm paying $1050 on Princess and $960 on Carnival for a cabin to myself, so you can see what I'm talking about if I don't want a roommate. Not that I have anything against having a roommate, but I'd prefer my roommate to be someone I'm attracted to and of the female gender. No exceptions on that one!
Your post was edited to remove the websites / agencies you noted that had non Carnival singles cruises. Can you write to me at my e-mail address and let me know the names of the sites you are referring to?
