Hey - great adventure and tale and I really appreciate the thread. I idolize Tonga Toast in the sense that it's really built up in my mind - enough so that I forget about it in reality every time - and then I get it and it's not as good as I've made it up to be. But hey - that's OK. I blame social media/social channels, as I feel like I see so many pictures of food from WDW before I've had it. And honestly, that's how I feel about Gideon's cookies. I see them + the marketing is so good by the Gideon team that I will always buy at least a few cookies in one go on a trip and then remember that I don't think they're actually all that they're hyped to be...
As a previous poster mentioned, I do agree that the Tonga toast recipe has changed quite a bit from the 2000's when I was first exposed to it. Or at least younger me doesn't remember it being so dry. There was more flavor + better texture on the earlier version. I'm sure if you were to make it at home with the copy cat recipes online (or the official recipe that we have in one of the Disney official cookbooks), you could alter it to your liking and get it pretty close to the OG. The other recipe that has changed for the worst over the years is the carrot cake cookie from the (former) Writer's Stop Cafe - now Starbucks Trolley Cafe. Don't get me started on that one. I think the carrot cake cookie has had a much drastic change for the worst though compared to the Tonga toast.
Anyway, I applaud you, Original Poster, and thanks for sharing the details of your adventure. I appreciate the time stamps. I might be doing the same journey in a few months if my mind idolizes the toast and my brain "forgets."
