I went to MiAdv july 13th and there was little crowd there. Max wait time for ST was about 10 min the other coasters was about the same the other rides were walk ons. I was there about 3hrs and did all the rides, except the water park, once and ST 3 times. For food i went to the picnic area they have and got a chicken sandwich with 2 sides and a med drink for about $6. it was actually pretty good. parking is i think $6 but if you leave the lot you must pay to get back in.
