Go on craigslist, you can meet someone at the park and they will let u in for 50 bucks, because it's 10 of you, might even be able to get them for 40 or 45 a piece. Good luck I use them every time and it works great. They might ask to meet somewhere else but they are perfectly safe usually gas station in very public places.

They are tour operators that but 200 tickets at the time, usually some tourist don't make it that day or rather go shopping, so they always have extra ones, and they pass the savings on to you, I have used them a total of 40 to 50 tickets in the past year, I have a lot of friends that come to Mco.
