The first trip we ever took to SDC was with our family, (The kids, at that time, ranged in age from 9 to 13) my sister's family and about 7 youth group members from our church. So, in all, we had about 17 in the group.
Not having been there before, we really didn't know what to expect, but we hoped that the high schoolers among us would have a ball riding every thrill ride in the place. As it turned out, they didn't do the rides much, and spent most of the time shopping...even the guys!!! So that was kind of a disappointment.
Then I had to take my minivan up to Ozark to a dealership to get it worked on, and while I was there I got a call on my cell phone--one of only two in the group--from SDC security. It seems my oldest son and his cousin missed their rendezvous time with the group and ended up at the security office. To top it all off we had an unexpected rain storm during the day and we had left our tent open, so when we got back to camp we found a lot of our stuff had gotten wet. I think that was the same trip where we had a several skunks roaming around our campsite. Looking back it's kind of amazing that we ever went back!
In summary, I don't mind going to SDC with a big group. I think in many ways it makes it more fun to share the experience with friends and family. In fact we're going to be there with a family group of probably about 13 in just a few weeks. However, you have to go into it with the understanding that you can't do EVERYTHING together. Like someone said earlier, it's just too hard to meet everyones schedules, needs and tastes. So we go into it with the idea that we'll go off in little groups to do what we want to do then meet for lunch or a particular show later for the big "fellowship" times. (The fact that we all have cell phones nowadays helps a bunch too!) My kids and I love Wildfire and the other rides, but my wife wouldn't be caught dead on them, and would rather shop, see a show, or maybe do a craft class. So we go off in little groups, to do what we enjoy and that makes it a whole lot easier and more fun for everybody.
