How long are you going to be there for? That can dictate your stroller choice. Kingdom strollers is great, you can find the stroller that you want and they will deliver it to the resort and pick it up and you don't need to be there. It's up to you if you want to decorate or not, but you are at Disney, that itself is pretty awesome. In all the years that we have gone, we have never decorated our room and we are usually there for the Halloween party. But again, its your choice. I know that it would be hard with the twins, but try to travel as lite as possible, you really don't want to have to haul a bunch of stuff if you don't have to. The one thing that I love it the Memory Maker, it's definitely worth the cost, tons of photo opportunities and all of those family photos that you will have forever. I love that item and is the one thing that I will always get when I go to Disney. Other than that, don't stress, this is, after all, the happiest place on earth!! Have an amazing trip!
