How old are the young kids? Are they setting up and taking down their own tent(s)? Setting up and taking down camp can take up 1/2 the day, between a 2-4 hour drive, not much else to fit in, potentially. Munising is close enough to marquette and big bay, for example. Monty makes a good point, it may be better to pick 2 locations.
Syl’s cafe in Ontonagon has good pie and pasties.
AJ’s Walleye Lodge and Oven - service was so terrible it was like one of those chain restaurants where the servers are rude on purpose. Avoid it. It’s in Bergland, on lake gogebic. If traveling from Lower MI - no need to see it.
Area around the porkies is a bit of a desert for restaurants. Unfortunately, in some cases that means the terrible ones survive.
JW’s BBQ is ok, not great, but decent. Family friendly, went with a 3 yr old at the time nephew and his parents.
I live in the region, feel free to ask me anything.
for a bike, I’d go with mtb vs gravel. Just in case you get the chance, noque trails in marquette and munising bay has good trails. Copper Harbor, Swedetown, Soke, Tech Trails, Ironwood are others potentially you could hit up.
For porkies - lake of the clouds has a few loops or out and backs that are good. Presque Isle, on the western edge of the park is a nice short 3 mile loop, near lake superior. This is where a little kid recently spent 48 hours or so lost, fortunately found. If your kids are prone to going off on their own - headlights, and whistles may be useful. Superior is still ice bath cold.
For camping reservations, I’d book sooner than later. I ended up at Twin Lakes state park a few years back. Was ok, but it is more of a powersports crowd (SxS, ATV) than silent sports. The ‘gravel’ path, only my buddy with a fat bike could ride it.
A cargo carrier - either on the roof or on a hitch can be useful. If you have to take down camp in the rain, for example - keep the mess outside the vehicle.
For making camp food ahead of time, breakfast burritos, each wrapped in foil, can be a good time saver. Same with foil packet potatoes. Cut up taters, add onion, butter - wrap in foil. ready to toss on fire. I also take a cast iron skillet and cook with it directly on the fire.
Have contingency plans for weather, uno, boardgame, etc. Hence the suggestion for a popup EZUP or similar shelter. Stuck in the car or tent is no fun for extended periods of bad weather. No movie theaters in western UP.
I can’t help with macinac. I hear the fudge is good. Have not been in ~ 35 to 40 years.
