Great value!
I really enjoyed my stay at the Aqua Grand. I had booked it online for really cheap, and when we got there, we were upgraded to beachfront rooms. The people were exceptionally nice, and the view was great. The pool is nice, but the hot tub in the kids' area was great. Free continental breakfast. Nice beach area. Great location for ferries and all of the shopping and restaurants in Mackinaw City. I would definitely go back, and I would recommend it to a friend. The "waterpark" is more like a "water playground," though. We didn't have kids with us, but it would be good for little kids, but it's not like you can spend days there. Still, a great value.
