We've been going to Disney for over 20 years (10 trips) and I've used the same Disney TA for the last 9 trips (did everything on my own for the first trip). I will admit that based on things I've read about Disney TAs (or more likely many TAs who just *say* they're Disney experts) on message boards and FB, we definitely have a great one. She's always available -- if I text/email her a question or request, I usually hear from her in a few minutes unless it's a question that's not time sensitive and even then, it's usually within an hour or two. I like that she's the one who watches for new/better deals to come out and automatically takes care of applying those rates to our reservations. I usually wake up to an email from her with our new reservation info whereas people who take care of their own reservations have to watch for those rates to come out and then modify their own reservation to get those rates. It's a little easier to modify your own reservation now (it can be done online), but in the days where the only way to make a modification was to call Disney, it was a nightmare with wait times of well over an hour on days that discounts were released. I don't know if this is still true, but I know at times in the past, TAs had earlier access to the discount rates (by a few hours) so their clients had a better chance of getting those rates. And Earmarked or Authorized agents have/had a special phone number to call with more operators and far shorter wait times than non-authorized agents. That might not be accurate anymore. On our trip in 2018 (I think), a new discount came out that was not announced ahead of time -- even to TAs (they got notified a few hours ahead of time) -- and many people missed out on it because they weren't on social media that morning and the number of rooms available at the discount rate was very limited. Meanwhile, my TA sent me an email at 5:00 a.m. letting me know a surprise discount was released and she applied it to our reservation. And the biggest reason I use a TA is that I like to support small businesses whenever I can. Our TA owns the agency and has 9 agents working for her. They're located all over the country (all working from home), but our TA happens to live about 2 hours away from us. So yes, I could do everything myself; but I prefer to support a small business and not have to deal with the details of the reservations for our trip.
