Our guide, Jordan, was lovely and knowledgeable, she did a great job. The criticisms I have below are all about how the tour is structured and is out of her control. Great work!
Firstly: Most of the food was quite good. If you're going to be in the area and want something to eat and aren't fussy and/or want to be surprised, this is a good bang-for-your-buck in terms of price over volume and I recommend you give this a shot.
For other foodies or alcohol enjoyers looking for a more elaborate tour, however, this does not provide that experience. We experienced 4 stops over the course of 2 hours, so you find yourself stationary for a larger proportion of time than the guide has information. The portions are large and while that is nice, the point of a food tour is to try a larger variety.
My advice: You should arrange for smaller portions in more locations. Even if you have to charge more, I think you'd get better experiences in the long run. Also, we were called the day before and asked if we want alcohol paired with our food, and we received a total of one 4-oz drink which did not taste like there was alcohol in it and was heavy (frozen), which compounded the issue of filling up too much and did not provide as much of a buzz. A buzz that would increase the satisfaction of your guests and will work to your favor in the review section!
We also expected more walking. The information section stresses the length of time on your feet but we only passed a fraction of the park as I understand it. People want to come see the sights, and extending the tour has an added benefit of exposing more of the area.
Lastly: The information our guide gave us was only about the history of the restaurants we visited. That is great and was interesting, but more detail on the park itself, Orlando, nearby sights, etc. would all be good things to add in transit or during tasting sessions.
This was average stuff, but with how cool the park is along with your talented guides, there is potential for a fantastic tour here.
