I've played Oakhaven many, many times and been in several outings there (2 last year and a couple more before that) and they do a SOLID job with handling the outing.
The price includes free range balls before hand, greens fees with cart, a better than average dinner after the round.
There is also a beverage Cart that runs around serving beer - they do a good job of keeping everyone wasted.
The prices that scarlet sent me are very good for a weekend rate.
Currently, I'm favoring Oakhaven because it's a known quantity. The only negative I perceive is that it's just north of Delaware City; not a bad drive, but a little out of the way for most people.
There are a couple other courses in mind that I haven't ruled out.
