Forget their 800 MHz transmitters, what about 500 people within 1,000 feet of you with FRS/GMRS radios yakking on them endlessly? I'd take leaky coax from a 50W transmitter 1/4 mile away than several watts being radiated within sight of me.
GMRS would probably work great if there wasn't so much co-channel interference in the parks. WDW's Nextel system is not sharing the same channels as the DTR/Trisquare radios, so even with a noisy transmitter it still won't cause as much interference as an on-channel source.
When I go there next I'd love to tape a VHF radio, UHF radio, and a DTR or Trisquare radio together and try them out under the exact same conditions. I'm sure the results would be interesting.
For the Hams, there are 2M and 440 WDW repeaters on property apparently. If this is true, coverage should be phenomenal, although you're limited to who you can talk to.
