I'm heading up to Great Lakes later this month (21-25) for my brother's NAVY Graduation thing and when we called the Ramada Inn the lady said that they're located right across the street from the park and that it'll be accessable to get into when we go. Thing is, is that when I go to their website is says they open May 1'st. Do they still let people in early, because I thought I read that they have some soft openings as the park gets closer and what not.
The "soft opening" is for private events only. It doesn't open for the public until May 1.
The Navy usually has a private party at the park the week of graduation. Check into that.
