Super cute pup - congrats!!
We've done several 2-3 week trips with our 2 active Border Collies at FW in the past few years. The key for everybody to have a good time is for us to make sure our dogs get a good amount of exercise each day and have plenty of goodies to keep them entertained when we leave them behind in the camper.
We have one dog that's not great with strange dogs, so he and I go out to the dog walk each morning for a good jaunt. DH takes our other dog to the dog park for a rousing game of jolly ball to get the zoomies out.
Once exercise time is over, the dogs are crated in the camper with plenty of stuffed chew toys. Usually we pack their breakfast in kong-type toys and freeze them the night before, so it entertains them and keeps them busy for a while. We also close the blinds (they don't bark at what they don't see), leave the TV on for them - Disney channel of course- and turn on either the fan or A/C for white noise. (What they don't
hear, they don't bark at either.)
It usually takes a day or so for them to get the new routine, and we do a few test runs to make sure they're quiet while we're gone. (Go out for a bit, sneak back, go out a bit longer...) We also check in with our neighbors and tell them to please let us know if anyone is making a ruckus - no complaints so far!
Knock on wood, but our system seems to work and everyone has a good time. I know it helps that our dogs go camping with us a lot. If you're planning to leave your pup in the camper, I'd definitely recommend some trial runs before you go to FW. That way you can figure out what works best for him so that he
and your neighbors are happy.
What also helps in our case is that we're not the type to do "commando" touring when we're at WDW. We typically go out to the parks for 5-6 hours at a time, come back for potty/dinner breaks, then pop back out for a while. In the evening the pups have play time in the camper... now THAT is a party with 2 active herding dogs in a 20' space!

We recently adopted another young border collie, so this year we're going to have to make some adjustments to juggle the 3 dogs

, but I think it will work just fine. She's already had some practice camping runs with us (something I'd definitely recommend btw) and she is a very adaptable, easy going girl that seems to take everything in stride. Plus she's pretty tiny and doesn't take up much space.
Good luck with your pup and I hope you all have a wonderful trip!
