I was wondering if or where I can find a map of the resort to see where the Diamond Club is situated
Diamond Club isn’t a place. It’s a kit of optional services any guest can buy, like a VIP bracelet.
Sanctuary is a place. It’s an adult compound within Grand Memories. Guests at Sanctuary also have a higher level of available services and guess what?
You can be a guest at Sanctuary AND purchase Diamond Club extras.
Here’s a link to property maps where you can see Sanctuary inside Grand Memories:
