Well I doubt that's the case especially for Tent sites. Disney at a minimum wants the pets in a temperature controlled environment. Do you have a tent or popup, Mad Stitch? Not to send this thread on a pet-loop-who-takes-care-of-their-pet-thread-that-ends-up-getting-locked. Pets and tents/pop ups don't mix well. If you have a travel trailer or bigger, then you shouldn't be in a Tent site.
So it's one or the other. Not much middle ground there.
For Preferred and Premiums, there are designated pet loops but the non-pet loops can be pet loops if demand overflows from the pet loops to non-pet loops. Only Disney knows when that happens. I believe all Full Loops (1600-1900 but not sure about 2100) are all Pet loops.
But pets and Tent loops are generally not compatible by the rules. If you're in a Tent loop, you have a tent or some canvas. If you have a tent or some canvas, that's not an adequate shelter for a pet. So the two don't usually occur at the same time. What type of camper/shelter do you have, Mad Stitch?
