I did use a TA for several of my recent cruises--and all of those I have planned. We had an issue with drink package for my hubby not showing up on his account. Even though she was on vacation and on a cruise herself --she got it sorted before dinner on embarkation day.
I found her through the boards--on one of my Roll Call a great lady who was always extremely helpful with all kinds of information and spreadsheets about excursions, and cruise tips was always raving about her TA for many reasons. Knowing its a no-no on the boards--I sought her out at the spillway and got the TA's name and number. Used her ever since. She's best on cruises, but will assist with flights and hotels--honestly I prefer to look and book those myself. Both the lady on the boards and the TA have become friends IRL.
One of the many, many reasons I love the CC boards!!
Sometimes she sees a deal, sometimes I do. Either way, no problem for her to check pricing for me at any time on something booked, and for a 9/2023 Med cruise we ended up saving $2100!! To me that was a win-win and basically covered nearly all our excursions!!
