I was organizing a bachelor party in Nova Scotia from Thunder Bay, Ontario, when i came across Splatz's website. As this was most of the party's first time playing, we had a few questions which the owner was more than happy to help out with via email, which made things very easy.
Prices were very reasonable and we were there for about 3.5 hours. When we did leave, it was only because we had a prior commitment.
The field size is pretty good. It was neither too big nor too small, so games didn't last too long but were not so cramped that you were out in 30s (except me, but that's just because i suck). Lots of natural barriers as well as a huge array of bunkers, towers and walls all over the course.
I definitely hope to play at splatz again next summer when i'm home. I don't have anything to compare this field to in terms of rating it, but since everyone who went had a blast and the owner was so helpful and accomodating, I'm giving the field a 10 for customer service, level of fun, and quality of the course.
