When your membership expires, you will keep any VIP dinosaurs you have hatched, don’t worry!
You will retain your current balance of Loyalty Points. You can view your balance at any time in the VIP sign up menu and continue spending them on certain Loyalty packs. However, there are some VIP packs that will be unavailable without a subscription.
The DNA production facility and other VIP-exclusive buildings will become unavailable, and any upgrades done on the building will be undone.
