Wi Fi

I'm a bit new to asking questions, so I'm not sure where I should ask this.

I used to be a member of "The Club" but have not had a van for a while and have just re-joined. Since I was last a member I see that a lot of sites now have Wi Fi. Is there an extra charge for this ?

We are planning a visit to Minehead Club site as a 1st trial of our "new" van in a week or so and was wondering about the workings of said Wi Fi

Thanks in advance, Tom.
