I haven't but since you're not getting any responses...There is no longer a direct bus, you'll have to change buses near Sea World. Looks like around 2 hours plus however long you have to wait at MCO.
The bus goes to the TTC not to SoG. You can't bring much luggage on the Lynx bus. Does SoG run buses from TTC to SoG? Probably luggage issues plus timing.
Doesn't sound like something I'd consider doing.
I'd use Mears shuttle for one or two passengers otherwise a car service.
