In my opinion, the race weekends are a little too similar to one another. I realize that not everyone feels the same, but I don't feel the pull to do multiple race weekends like I used to. Overall, I prefer morning races, but I LOVED the couple of nighttime Wine & Dine races I did - the atmosphere just wasn't the same to me when they made the switch to daytime. And every other race weekend is a morning race, so it's disappointing to me that there are now zero nighttime options.
I do think that they made these changes (boosted capacity, made the weekends 5K/10K/half marathon format, added additional purchase options like early expo access) with profit in mind. They make more money if they over 5K/10K/half marathons as opposed to just the Expedition Everest 5K or just the Tower of Terror 10-miler...more runners can run, so more money made the expo, hotels, etc.
As for the surveys - I took a couple of their post-run surveys and thought some of their questions were worded in such a way as to get them the answer they wanted...
