Hi there- we are looking to get the best rate possible on our cruise, and have considered quotes through Dreams Unlimited, Small World Vacations and Costco. What experience do you have with any of these agencies? All quotes are relatively the exact same with the same offerings, so I'm wondering how to choose on (literally two of them have the exact same quote & OBC offerings). Is OBC negotiable? Will TAs add on upgrades or extra OBC for booking with them over another one to secure business? I typically do my own bookings, but was considering a travel agent this time around. Thanks for any info you can offer!
