The Fairgrounds is a terrific spot for a large frag swap. The issue was with the increase in major manufacturers attending and the need for them to have the space they required, the fairgrounds just didn't work any more.
I totally get the nostalgia for the old RAP, but that ship sailed a long time ago. MACNA was dying even back then and the need for something more than a swap was real. It was a logical next step.
I agree that the parking is a major PIA at the hotels, but there isn't any other places large enough. The Marriott and Hilton are the largest rooms in the county that aren't private or are named the Anaheim Convention Center...
Every year (when I was doing what I did) i would have the Convention Center rep hit me up and ask when we would come talk to them.. the issue with them was they were WAAAAAAY more expensive.
One thing most people dont realize is the cost of the room itself is well into the high 5 figures. We would offset the cost of the venue with "room night" sales. If enough room nights were sold, we were able to offset the cost of the venue itself to a point that the show remained "profitable".. Having the major manufacturers helped this immensely becaue they are all over the country/world...
Trust me when I say RAP is a major undertaking.. Over a year in planning for the next show and contracts signed 2-3 years out....
Fairgrounds shows WILL happen again, but not a "Reefapalooza" in its current form...
