I just had to google what that is. It does look pretty great! Not sure I can justify the extra $60, but nice to have that option!!
Hmmmm I'm thinking with tired kids, getting back to the resort quicker might be helpful. The fun of the monorail after Illuminations may be a better idea in theory than real life!

Thanks for the tip!!
This is what I do. I park at Epcot and before even entering the park I get on the Monorail and go to MK. I spend what ever time I want there and then take the Monorail back to Epcot, watch Illuminations and then go to the parking lot and jump in the car.
For the rest of the stuff, it is possible to use the extra cost stuff, but, frankly you couldn't force me at gunpoint to spend money on that when I had my car right there. It does take a little time, but, not all that much to drive between places, however, I have never found it that much of a burden and it breaks up the time a little and gives the kids time to decompress between parks.
Animal Kingdom really is the only park that is a ways away from either the Monorail or boat or bus transportation. If for example I decide that I am going to split my time between Epcot and DHS I have parked at DHS and taken the boat to Epcot. That is more of a strain coming back at night, but, it is a relaxing ride.
My way of looking at it is, I'm on vacation, I am not going to run around like a beheaded chicken while on vacation. I will sit back and enjoy my total experience and part of the total experience is getting from one spot to another. when it comes to DAK, I take my car and drive to the next park, it is much more convenient at the end of the day and isn't all that much of a hassle, at least not to me. All that said, with the exception of MK and Epcot any and all inter-park transportation can be frustrating. Even the high price one, only gets there at certain times so you have to wait or leave earlier then you might want or later, and you have to figure all that out. The special Express is not on demand, it arrives at scheduled times and is subject to traffic problems just like all of the buses. What that means is that with the exception of MK/Epcot I just used my car almost every time and I park hop with the best of them. Sometimes 3 a day. Haven't quite found the need for 4 yet.
