to the DISboards!
Please don't feel like you shouldn't have posted, you raised some very good questions and generated an interesting discussion that was different from our usual dog-related threads.
I'm not a dog owner (though I have been an Aunt to several Very Good Dogs), but I would say that the four Disney resorts that now allow dogs aren't exactly dog-friendly, but more "dog-tolerant." Do take a look at our FAQ thread up at the top of this board and check out the rules for where dogs are and aren't allowed on resort property.
It also concerns me that you say they're super-excitable, as the resorts won't tolerate excessive noise from the dogs, whether you're in the room or not. If you're at one of the evening events and the dogs start barking, you'll be required to return to the resort within 30 minutes, which ain't easy.
I agree with the poster who said that a Fort Wilderness cabin might be a better fit for you, especially since there's a dog park right at the resort.
I don't want to be discouraging, but I think 16 days at WDW would not be my choice of a first vacation with a couple of dogs who are excitable and not used to travel. Some dogs are great travelers, some...aren't, and it would be pretty awful to realize three days into a 16 day trip that it's not working and you need to go home. I strongly recommend that you try some shorter trips at hotels closer to home just to see how they do and get them used to overnight stays in strange places.
You've noticed that we don't get a lot of posts about bringing dogs to WDW, and that's probably because a WDW vacation is generally focused on activities you can't do with your dog - theme parks, recreational activities, shopping, dining. Dogs aren't allowed in any of those places. There just isn't much to do with a dog at WDW besides have it in your resort room or walk it in a designated area at the resort. The dog-friendly resort policy and the Best Friends kennel are intended more as a convenience for guests who don't have options for boarding or pet-sitting at home, not really as a "hey, bring your pupper to Disney and have fun vacationing with your dog!" kind of thing.
The other issue is the walking that you mentioned. WDW is not at all like
Disneyland. It's theme parks and very large resorts connected by high-speed highways without sidewalks; guests ride buses, monorails or boats to get from place to place (none of which allow dogs). Of course, you'll have your car, so it's easier to get around, but still, there's nowhere you can really walk to from AoA.
It's your call, and again, I hate to be a downer. Maybe they'll turn out to be happy little travelers.
