I've done this same basic tour at Busch Gardens and it was $200 per person, so $400 for me and my wife and it was great. (Also, the tour guide had a camera and took pictures of you doing all the various things and then you could buy a CD of all the pictures they took for $40. I think the price on that has gone up, though, because that was an amazing steal.)
Would I spend out of pocket for this? If I were bringing a large group of new visitors into the park during a very busy time of the year, yes.
If I were just with my immediate family and looking for a good skip-the-lines upgrade to a theme park vacation, I'd opt to stay at a Universal Orlando resort hotel and skip the lines there, instead. I think that's the better financial deal for a solo visitor, family or small group that's interested in those parks.
If I wanted to skip the lines at Disney in those situations, I would look to visit at another time of year, or make aggressive use of our theme park voodoo strategies (arrive at opening, juggle FastPasses, eat at off hours, leave high capacity attractions for middle of the day, meet characters at Epcot World Showcase, etc.) to minimize waiting time.
I love to get more behind-the-scense details, without all of the false information. BUT, unlimited FASTPASS, count me IN.
I have used the expensive VIP passes from Universal and they have been WELL WORTH the money...expecially on their "Fright Night" tours...not for young children!!
Save a space for me Mickey...I'll be there with EARS on!
