a few assumptions.
1. you are interested in LE/Fire-EMS comms.
2. you have a P25p1 capable trunking scanner
here is a summary:
Orlando / Orange County = all LE comms for the county, the city of Orlando (and the other smaller cities) = encrypted. Fire/EMS in the clear.
Orange County Trunking System, Orlando, Florida (radioreference.com)
Osceola County = all LE comms encrypted - Fire/EMS in the clear. of note, if you program this system, be sure you program the interoperability TGs as they are in the clear and can be entertaining (cross jurisdiction mutual aid, etc.)

Most all the theme parks are encrypted and/or not monitorable (Disney) - with a few exceptions for the parade and some of the smaller venues.
most of the hotels and other attractions are either analog or DMR - YMMV.
if you search for "Disney" in this forum, you can read some of the older posts.
finally:
wear sunscreen and/or a hat.... hydrate.... stay cool -- and be ready for massive crowds.... the parks and the area over there is busier now than it was pre-COVID.
