Yes, with the HB package you can order off the regular menu as well as from the dining package menu, but you will pay the dining package price regardless. MMM viewing from the ROA is fine, but not quite as immersive as it is from Main Street or from IASW. But it's also not as crowded, and you won't have to wait for your spots since you'll already be there. How long you wait to line up for your viewing area depends on how much you care about where you sit. If you really aren't that picky -- you just want to be in the reserved area and can see from the back just fine -- and the parks aren't that crowded that day -- then, technically, you could show up 15 minutes before the show and find spots. If you are picky about viewing spots, then I would invest more time in getting there early -- 60-90 minutes before the show should get you prime spots. Maybe you could get your spots, then take turns taking the boys to the restroom and walking around and getting a snack to bring back before getting the next kid for his turn. By the time you finish, the show should be about to start.
