Hi,
The only current one i know of is swan/dolphin. However you might have heard about the hero's getaway plan that happened in april 2002. After sept 11, disney offered a 2 week peroid Anyone from the Police/Fire/Ems from nyc could go and stay onsite and get into all the parks for free. If you had a 8 days room booked you and all the members(limit up to 5) got free park hoppers for the same lenght time. From what i'm told many police/Fire/ems workers from many different cites besides nyc tried and were allowed to book this with no problem. A lot of my guys from the FDNY here in nyc did go and had a blast. That is the only one i know of. Check with your union, i know the union of the FDNY offers very good discounts on off site hotels and discounts with car rentals as well as many other places in orlando.Also some time ago jetblue and american airlines used to give you $10 off any round trip fare anywhere if you were police/Fire/Ems or military. Since the tax increase after sept 11, i was told they stopped doing that. If never hurts to call and just ask and try, so give it a shot the worst they can tell you is no.
