Aloha SP is nice however it's a favorite of the S.E. Michigan large population area residents and they keep it really full and we don't like to make reservations ever if we can help it. We most often RV impromptu on the spur of the moment! So we usually avoid Aloha since it's out of the way for us and Burt Lake SP is right off I-75 and on Burt Lake with an excellent boat ramp in the park with lots of paved large vehicle parking and it's free for registered campers or annual $10/yr paid extra with our annual vehicle license tag.
All Michigan SP's entrances/use, trails, ramps and so many other things are included at no extra costs by having the cheap $10/yr "P" on your Michigan registered vehicle plate. There's an annual permit sticker for out of state SP users also that give unlimited use at any SP for the whole year. If using any Michigan more than 3 times in a year, the annual permit is the cost effective way to go. Burt Lake SP is also next to to the long inland waterway system by water that connects many gorgeous inland beach sand bottom lakes and little towns etc all the way from Lake Huron at Cheboygan to just north of Petoskey with bouyed well marked and plenty deep enough rivers and channels and it has 2 locks on it also. Takes about 2 days to enjoyably go from one end to the other in just one direction unless you do high speed boat travel and there's no marine sheriff boats (there's a lot of them!) that see you in the rivers and channels in the no wake etc areas. Lots of 35+ ft cabin cruisers use the neat Inland Waterway daily. There's several other inland waterway systems in Michigan also and over the years, I think we've done them all at least once. We're "boatnutz" also!
