The voucher lets you park closer to the entrance of the parks, but of course still have to pay for parking. We have used it several times. Works great for all the parks except for the MK. You still have to walk to the TTC and ride the monorail or take the boat. We found the bus from our resort faster, but if staying off property I guess that wouldn't be an option. Was really nice for EPCOT. Walked right into the front gate in less than 5 minutes. It is also blacked out on certain days--Christmas, New Year's, etc. If you can get one, you will probably enjoy using it for certain parks.
