As far as I know:
1) There are no plans for Sunpass to work with the EZPass system. They are a completely different technology that would be very expensive to get to interoperate.
2) Edd, the "Sunpass" offices you mentioned are actually E-PASS offices operated by the Orlando-Orange County Expressway Authority, the toll authority for most (but not all) toll roads in Orange County. You can test EPASS there but I'm uncertain if their devices will test Sunpass.
3) Once you activate a Sunpass, it usually doesn't begin working until the next day. Drivers should not plan to purchase a Sunpass upon arrival in Florida and expect to use it immediately.
4) No one will get a ticket for one or two missed tolls. When skipping tolls becomes a habit you'll be mailed a Uniform Traffic Citation (a ticket).
5) For those interested, you can purchase a Sunpass transponder at Publix and CVS stores throughout Florida and then call in to activate it. If you want it working before you get here, order via the internet from the
www.sunpass.com website and activate it ahead of time. Sunpass is also sold at service plazas on Florida's Turnpike. Those of you in Orange County can also purchase an E-PASS from an E-PASS Service Center: there is one on Goldenrod off TOLL 408, on SR50 at Kirkman and in the West Oaks Mall center court in Ocoee.
6) Sunpass is the state-wide system good on all toll roads in Florida and on nearly every toll bridge. E-PASS is Orange County's system. O-PASS is Osceola County's system and LeeWay is Lee County's system. THESE
ARE ALL INTEROPERABLE and you can use any of them anywhere in the state. This is different than EZPAss which is the system used in the Northeast United States and EZPass does not work in Florida and none of the Florida systems work in the Northeast. I-PASS from Illinois is interoperable with EZPass of the northeast, but also does NOT work in Florida.
7) Don't even get me started about PikePass, K-Tag, FasTrak and all the others!!
