How many of you simply don't bother with hookups?

Since we prefer to travel during the Winter months to cold/snow areas, we only hook up to the water or sewer once a week or so just to empty our waste and top off our fresh water tank. To prevent freezing we usually will not let our fresh water tank to get below 3/4 full.
We do have satellite so we don't have to hook up to the parks cable but we do like to hook up to 50 amp service. We can get by on 30 amp even in zero temps but it makes it easier to have 50 amps.
