Your sister will be able to come to the club as your guest.
We look forward to seeing you both

Hi I am a member of the club , was just wondering if I’m able to bring a non member ( my sister ) with me in a couple weeks time , or Does she need to get a membership ? Many thanks

The simplest way is if you already know at least 2 members then visit the club ask for a membership application form and get your friends to propose and second you.

How easy is it to become a member
