Haven't stayed there, but just DH and I find the deluxe studio cramped. Of course, our experience is somewhat affected by needing an accessible one, single bathroom in those which takes up space.
I'd say the decision depends on whether floorspace and two queen beds (resort studio) are more important than two bathrooms and a kitchenette with sink now that you'd have a Murphy queen instead of the not-so-comfy sofa bed (deluxe).
The resort studio has a sort-of food prep area requiring using the bathroom sink for cleanup. It does have a microwave and "beverage cooler." If counting on keeping any foods safely chilled for very long, you may prefer the deluxe's actual minifridge. The built-in caddies in the door of the mini-fridge are very useful for storing soda cans and other containers to free fridge space. The beverage cooler has none, only a flat panel door.
Also, you'll dash through the rain, if any, to get from BPK to the main building or to Gaspy's entrance. No canopy such as from VGF1 to the GF's main entrance.
Those would be my considerations if doing a girls trip. Hope this helps you decide.
