We normally also pick our own sailing, cabin, etc. We need little if any help on the research. BUT...
Once we booked a Cat. 1 on Summit at a special promotion price. A couple of days later, our TA emailed us that she could put us in a Cat. 3 (now FV) corner cabin for the same price... do we want it? You bet we did... the best cabin we've ever had... THAT'S GOOD SERVICE.
We were booked to go on Infinity to Alaska. A couple of days before we were to leave, Celebrity cancelled the cruise (azipod problems). We already had vacation planned for 10 family members. We called our remote TA and told her we needed to use this vacation time. There were no other Alaska sailings available, but there was a sailing available to Bermuda. Of course, Celebrity refunded the money for the cancelled cruise and offered a free cruise to those affected on our sailing. They didn't even have the notice out yet, but she literally stayed up all night getting things arranged with Celebrity, and all ten of our family was transferred to the Bermuda sailing, and the cruise was at no cost to us. THAT'S GOOD SERVICE.
Most of the time, nothing goes wrong, but if it does, I'm comfortable knowing that we have someone who will work so hard to get the best for us.
I have other stories, but those are two good examples.
(Thanks again, Lori)
