Club Site Storage Question?

Hi

We keep our caravan on the driveway however we are considering storing it at the new club site at Strathclyde park during the winter months the idea behind this is that we will get more use of the van during the winter months and also it will free up a space in the drive for a few months. My question is when you are taking a storage space do you have to take it for the whole year or would we be able to take a space just fron October to March. We don't want to store the van away from home during the summer months as we use it regularly so would prefer to keep it at home during the summer.

Many Thanks!
