Keep the seasonals/long terms and short term customers in separate loops. We frequent a CG that does this and it's a great setup.
Enforced quiet hours. Especially if you are catering to families, big rigs and seasonals. Most people don't always realize they are really loud and will be more than happy to quiet down by the owner or staff when asked. For us nothing ruins a CG more than a party atmosphere with hooting and hollering all night long that shows disrespect for others.
Have a conversation with local law enforcement and found out if they will back you on kicking out trouble makers. Ask them how you should handle these kinds of situations especially drunks causing problems. You can't always kick them out. This and the quiet hours enforcement will set the tone for the type of CG that's inviting for both seasonals and weekenders.
If you are looking at having long term customers then laundry facilities are a must. Even we use them when doing a week long trip.
