Over the past two years or so, I've left my little one with them roughly 4 or 5 times, including one overnight stay during Coasterstock this year. The facilities are very nice and clean. The staff is super friendly. My dog seems to love it there.
You can even get a cage that has an indoor and outdoor section (as long as it's over a certain temperature).
My dog and I both have separation anxiety when leaving each other, and they're accommodating for that as well. I was able to take her into a big play room in the middle of the day on my lunch break away from the park.
Thumbs up to Red Dog from this guy.
