Jason,
Can't say enough about Calusa, one of the best experiences in golf, the clubhouse and locker room make you feel like it has been there for ages.
The golf course is very very good, I thought the conditioning was fantastic. I really enjoyed the fact that it had a short par 4 on each 9 that can offer an opportunity at Birdie (I missed two short putts) and can also trip up a round (different 4 hdcp's in my group doubled each of them from the fairway).
Hope your friends enjoy it as much as I did.
Mike
