We've used it twice on the way in, once to the Pop, once to 192. Both times it's so painless compared to fighting I-4. Not sure it saves an hour, but it saves a good half hour to 40 minutes, IMO.
If you're coming south on the Turnpike, this is the ONLY way to go. Well worth the $1 toll each way. (I think it's a $1, could be wrong.)
