Some unsolicited advice: unless you are going on a day when AK is open late and/or you plan on coming back to AK on another day, I would think twice about going outside the park for lunch. AK is open fewer hours than the other parks but there is much more to see and do there now than just a couple years ago. If it is only open from 9-5, for example, IMHO it is impossible to see everything in that 8 hours even if you stay inside the park for lunch. By the time you walk from wherever you are in the park to the front gate, wait for an AK bus (I believe they do not run as frequently in the middle of the day), ride to AK, walk to Mara, have your lunch, and do the whole thing again in reverse, you will probably spend 2 hours or more. If you've got to have those zebra domes, think about doing Mara for dinner or just a snack (or better yet, Boma for dinner) after the park closes. JMTC.
