Planning Disney vacation for my son's 5th Birthday in October (his first trip)! Debating whether to book DVC Poly or GF studio? Our top choice is Poly; however, nervous about the construction. I know it's impossible to know status of the work this far out, but if the decision was up to you, what would you choose? We are a family of 4, our daughter is 9 and has been to Disney before. Want the trip to be fabulous for the little guy.
