No expiry dates — use them across any of my classes, mix and match. You'll need a pass to book a class; grab one below and you're in.
Log in to buy a pass, or book a class to create your account — you'll be prompted to set a password as you go.
Passes are paid by Revolut. Once Danica confirms your payment, the credits appear on your account and you can book — she confirms as soon as she sees the transfer.
