Are you wanting to go for just the day/ 1 visit? or are you looking to visit here a few times during your vacation?
I haven't found any discount tickets for a day, except as a Previous poster stated, just the 1/2 price when offered outside, and normally during peak or holidays I haven't seen it offered. On line -It shows that tickets are 45.00 (39.00 for a child 3 -10) at the door or if you order on line 40.00 (35.00 for a child 3 - 10) -
If you are doing multiple days in the parks, you might want to added it to your park passes this will save you some money, the water parks and more option is what we did before we moved back to FL. and got our AP's back . This way you could go in the evenings or earlier in the day when the crowds are lower here, also when its raining was another good use of this venue. We used this option a lot when the parks are the most crowded and its hot and humid out. We would head over to Disney Quest, for several hours for lunch or snack, and play game, it was a great way for the kids to burn off some steam.
