I thought it was worth every penny. We only had one good day, and this moved us around the park and backlot very efficiently to see almost everything. If you get there early, you can go ahead and check into the VIP area. We ate a little breakfast and watched everyone coming into the park from the balcony.
We went on a Friday in June, and during the afternoon, I was very relieved not to be fighting those crowds! I moved out to one of the Universal hotels for that part of the trip - we did all the Disney stuff then moved and did Universal, the WB Tour, went to a show (the whole purpose for the trip), and did the Hollywood touristy stuff.
