We are going to the world in September, we are wondering how cheap we can get Univer/IOA tickets? Aren't there b-fasts you can do and get one day admissions for free or something? Please give me the cheapest price out there and how to get them. Also, we have two small children around 6 and 3 who will probably not get a whole lot out of IOA but we still want to visit. Thanks for any tips!
