I'm not sure what a previous poster meant by a requirement of having a driver. Many teams don't have a specified driver and if you only can book a mini-van, you will have more room if you share the driving among the runners.
If you have even ONE local, however, you will be required to provide THREE volunteers, which a major pain in the butt. The race appears to hold back the "good" assignments for their favored teams and more than likely, unless you register your volunteers within minutes of the signup for volunteers, they will get sucky assignments (like middle of nowhere in the middle of the night).
I think HTC is telling people that only 1 in 4 teams makes it in from the lottery. If you have a fairly good sized group that wants to do it, go ahead and enter the lottery. I'd suggest having people put up their share of the entry fee now, with the understanding that if they bail, that their replacement will reimburse them.
I've done it for 19 of the last 20 years and this year was the worst yet, more so than several years ago when they somehow managed to have 80% of the teams converge on the same one lane stretch at one time.
In the 90s, there were lots of fast and competitive teams and it was pretty exciting, but now most of the teams are so much slower (30-36 HOURS) and non-competitive. Because they are moving through the course so slowly, they clog up the exchanges creating insane traffic delays. HTC starts them as early as 3 am (!!!!) on Friday and for the last several years, there were only a handful of teams starting in waves at 3-4 pm, and then a complete break until the "fast" teams started at 5:30. They used to have the fast teams start at 7 pm, and all the previous waves would have 20-30 teams - which meant that you got to see the super-speedy teams in action. No more.
We have an "automatic" entry (top 6 in each division get to by-pass the lottery), but honestly, it's not nearly as much fun as it used to be. And the management cannot figure out how to allow teams to run without the massive traffic problems. They are solely motivated by the tons of money they make - and it doesn't seem like they care about the runners.
If you do get in - find housing in Seaside and find vans as soon as you can. Bringing vans in from out of state is a solid plan and borrowing them is great too.
