I also like to book the suite I want, that way we are not disappointed - we get what we've paid for, plus we'll enjoy the cruise much more. Guaranteed - only means you'll get someplace on the ship, maybe a better cabin-but not the location you wanted. Waitlist, maybe you won't be going at all. The only way I'd do a waitlist is if I couldn't get the suite I wanted, but I'd be happy with what booked if I didn't make the cut.
