This could be a crazy idea depending on how you value your time. If you haven't visited the parks several times- and want to maximize your time experiencing attractions- I would not leave the park. It sounds like it's close and will be a fast turnaround- but the reality will be very different. By the time you exit the park (which is a hike in and of itself), wait for the bus, order, eat, wait for a bus to return, and walk back into the area of the park where you can begin to experience attractions again you are looking at well over 2 hours- probably closer to 3. We love AK and AKL, AKL is pretty much the only place we stay these days. With that said, you can see the animals on the safari attraction. Have lunch in the park at Yak and Yeti if you want to do TS- but I would pick a counter service like Flame Tree Barbeque if you haven't been to WDW a lot. AK is a short day- and if you want to see and do everything sitting down for a TS lunch is going to take a minimum of an hour- and most probably much more than that if you need to wait for a table. Once you have lunch at a counter service restaurant, queue up to do the safari a second time. I can guarantee you will see many more animals doing it this way and still come out way ahead on time. On the flip side of the coin, if you have been there many times and don't value maximizing attractions, Sanaa is a great restaurant. I would personally do CS for lunch and book Boma for dinner. Sanaa is good- but Boma is far-and-away the best restaurant within the AKL complex if for no other reason than the sheer number of choices you have on the buffet. We have eaten everywhere there is to eat there multiple times, done all the special safaris with dinner included, etc., etc., etc. Boma for dinner is your best bet IMHO if you want to experience AKL while you are in the AK area and haven't eaten there before. Depends on your priorities.
