I work remotely for a company in Ohio and will be heading back to the office 8/7 - 8/17 for my quarterly visit. I'm bringing my kids this time and would like to take them to Kings Island this year (we did Cedar Point last year). I figured 8/16 would be a good date since it's closer to school starting (I guess some schools in Ohio even start before then) and Sundays are usually less crowded but I see that Kings Island says this is National Rollercoaster Day. Is this actually a big deal that will make the park more crowded? If so I might shift my plans to go the previous sunday (8/9). I'm thinking I'll buy Fast Lane passes for my kids since it's likely to be fairly crowded this time of year (we lucked out at Cedar Point last summer, there was almost no one there and we got on almost every ride in less than 15 minutes, but I don't think we'll get that lucky again). Or would the Fast Lane pass be less useful on a sunday?
