Go the the Pages menu in your WordPress administration. Select a page to edit. In the “Document” boxes, you will see VIP checkboxes, one for each VIP Lounge. Check the boxes for which you want to restrict the page visibility.
If nox chekbox is checked, the page is visible for everyone.
If your page is linked in a WordPress Menu, the menu entry point will also disappear for users not allowed to see the page.
