I think that they were saying that they were considering it last year but it was booked and they couldn't grab it.
I guess the question would be how many people can fit there. How many campers, tents, and cars? I know that it was stated that there was a 10 car max but that this wasn't impossible to add a little more. If we were to add up all of the Camp and Fly people who came last year we'd exceed capacity so there will be others who would be camping at their own site. The last question would be how much further is the walk to where we fly? I can look at a map and check that out in a bit. It was super convenient last year but the extra walk wouldn't be too bad I'm sure.
Personally, I didn't see any flaws in our set-up last year and we were super close to the flying site, and we effectively had that entire site filled with people who were flying, but I also see the perks of this group site as that grill is perfect for bigger dinners and there's a bunch of tables. I'm open to exploring the options. There's pros and cons to both.
