We had a significant flight delay in the morning, but it was all still worth it! Without our guide, Tikal would have been just a pretty walk, but with the guide it was full of amazing history and context that we would not have received otherwise. The lunch was served in an outdoor restaurant and the food was excellent. It was a great way to start a big day of walking. Overall, the sheer historical depth of the site, and the vastness of it is mind-blowing. For sure, it is a full day of walking and climbing, bring walking shoes, water and snacks. If this trip is in your price range, or at the edge of it, I recommend doing it, this trip is is worth every penny. (FYI: for nervous flyers, know that the planes we flew on were very small but the flights were short and it was still worth it.)
