|Your diagram looks good and that setup should work nicely.|
I think though, if it were me, I'd use class A in the office (ie: 10.0.0.0/24) and the class C (192.168.0.0/24) in all other areas. Then you have a little more separation and less chance of anybody sneaking into the office network from the public ones. Also, it makes it easier to keep the two different areas (public vs private) straight in your head when thinking about the IP addressing.
Also, if you have layer 2 equipment, I would definitely make use of VLAN's to also segregate each network.
The only negative comment I have is your diagram, you've labeled your Bar and Pro Shop area's with "WAN IP" The separate pieces of your network are all part of the same physical location. A "WAN" encompasses two or more physical locations. This is just one. But that's just nomenclature and has nothing to do with functionality.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
