We got in line at about 8:30pm on Sunday night, after a brief bathroom visit/beer at Bruno's. We were headed to our camp at about 12:25. We had lots of fun dancing around the line, playing music, talking to people, and sharing snacks. I had hoped for it to be quicker, but 4 hours didn't seem absurd considering how thoroughly they were checking for stowaways this year.
For example, we drove up in my four door sedan, which was packed to the brim with almost all of our shit, the rest having gone up in our truck a few days earlier on someone's early entry pass. I have never used a bike rack. I acquired a trunk bike rack from a friend. I attached it incorrectly to my trunk. During the 6 hour drive to the event, the weight of the bike rack pushed against the rear bumper and pulled against the back of the trunk opening, resulting in distorting the trunk's hinge orientation, literally pulling the trunk lid half an inch out of place.
The ticket-tearer/car searcher told me to open my trunk. I said I'll have to take the bikes and bike rack off my trunk to do this, this trunk is not opening with this crap attached to it. They took this to be sort of excuse and my refusal to open the trunk, and were kind of aggressively rude to me about it. I was merely honestly explaining the situation I was in, and that getting into the trunk would take a while, nothing more. So my partner and I get out and start unlocking/unstrapping the bikes. Another gate worker person comes by and starts giving us a hard time for doing what we are doing, that he'll just help me open the trunk with all the crap loaded onto it. I calmly explain the situation to him - no, you can't. This bike rack broke my trunk, see? I have to take everything off to open it, otherwise it will get worse. He didn't want to believe me, but whatever. We finally get everything off and the trunk open 15 minutes later to reveal: A tightly packed trunk full of lots of shit.
I sighed at the mess strewn around my car, they gave me the thumbs up after groping through my trunk stuff, and I calmly began the process of re-attaching the bike rack (this time correctly). The little darlings who had checked my car, rather than offering to help expedite the process by assisting me with reconfiguring and attaching everything, exercised a decent level of impatience and annoyance at the time it was taking me to get everything in order again. Dude even told me to just strap my bikes to my spoiler and keep moving, it wasn't that much further and I'd only be going 5mph anyhow. I briefly fantasized about smacking his stupid top hat off his head, smiled, and finished up getting everything on my trunk properly.
The gate-check experience last me about 25 minutes. One car. 25 minutes. Apologies to anyone who was behind me in my lane, but all I can do is shrug. And I'm still cranky about my poor trunk lid.
I don't think that was an answer to "How can we reduce the wait time to < 4 hours?", but may perhaps give some perspective on the issue.
