Use of VNP's Clubhouse is governed by rules described here during restrictions imposed due to covid-19.
To make a reservation,
Click on the green "+" in the bottom right corner of this page.
Enter your email address on the next page.
On the next screen you will be asked to set up a "calendar" account if this is your first reservation. If you already have a "calendar" account, you will be asked for your password. This account is only for the Clubhouse/Pool reservation calendar, not for the VNP website. So, no need to access the restricted area of the VNP website by clicking on "Log In" or "Register" in the upper right corner of the screen.
On the next screen, enter the day and time of your reservation. Reservations are limited to a maximum of 1 hr., including a 10 minute vacancy break before the next hour begins, and not more than one day in advance. Just to be clear, your reservation is actually for the first 50 minutes of your 1 hr. booking.
Enter your unit number in the Booking Title box.
In the Spaces box, select VNP Clubhouse & Pool.
Then enter your name and phone number in the appropriate boxes.
You will receive an automated confirmation email and your reservation will appear on the reservation calendar.
