Of coarse we use discounts, everyone wants to save money. Why do you think we have so many parking threads?
I bought the Florida Fun passes for BGT/SFW. The offer just expired, let's me get into both parks for the rest of the year. And I have to activate it before the month ends, going this weekend.
That was a good article, had web sites of all the parks. If you can't find coupons locally, then call the park and see what they have.
Last year when visiting SWF, we stopped at a gas station just to buy a 2 liter bottle of Pepsi to get a coupon, it worked, saved us a ton of money.
If all else fails, walk up to the ticket window and look around, people will leave extra coupons on the window sill. Snatch one and get in line. Did this at SFGam last October, it worked. Why not? That money can buy my lunch.
