Proportion of Serviced v Standard Pitches

On my last visit to a site with SP during the week, there was actually a greater occupancy on one day on SP rather non service pitches. Most sites run at about 10% SP but this one has a third of pitches being SP. Again just one day and the SP were full before the rest of the site was. They do appear to get booked up early and before non SP pitches on sites where the number of SP is about 10%

Also while it may be true that people book them to secure a HS, but on the sites I go use are all HS and again SP go first, with motorhomes and caravans too, often 50% MH on SP. 

Possibly because Carnon Downs basic pitch price for 2 adults & 2 children in August is £41 a night, whereas, for example, Treamble Valley is £33.40!

The club clearly has a pricing strategy which works as far as service pitches are concerned. On our recent stay at Putts Corner there was never more than 1 vacant serviced pitch, even midweek. They're not for us but certainly seem popular with lots of vanners and MHers.
