My review:
I took the tour on 3/7/2016, and I checked in around 8:15 a.m. I was told to check-in to Tomorrowland Terrace at Magic Kingdom no later than 8:30 a.m, but the tour didn't officially start until about 8:45 a.m.
There were 21 people in our group and 3 tour guides. We stayed all together and would only split up with one tour guide when we went to another park. I really can't remember their names, and I didn't really care to catch them. Most of the time they joked about this being training for one of the guides, so I don't know if we got the full experience.
We walked to Space Mountain at 8:45 a.m, and waved to all of the people standing behind the ropes to Tomorrowland (jk on the waving), but we were getting some looks. We then waited by Space Mountain until 9 a.m. (park opening). That was very amusing, because we got to see the stampede of people breaking every rule of Disney trying to be first in line for Space Mountain. It was rather hilarious, but now I have a greater appreciation for the CM's that handle that crowd every morning.

Schedule:
Ride order in MK: Space Mountain, Seven Dwarfs Mine Train, Haunted Mansion, Splash Mountain, Big Thunder Railroad, and Pirates of the Caribbean (surprise attraction).
After those rides, we transported to EPCOT, and got to walk backstage of The Land Pavilion. This was cool, because you get to see backstage of pretty much every World Showcase Pavilion before reaching The Land.
While at the Land, we had lunch at Sunshine Seasons. Honestly, it was ok. Nothing special.
Ride: Soarin.
After riding Soarin, we then went back to our transportation and drove to Hollywood Studios.
Ride order: Rock N' Rollercoaster, Tower of Terror, Toy Story Midway Mania, and Star Tours.
After Star Tours, our guides said goodbye, and our tour was over about 20 minutes earlier than scheduled.
Bathroom/snack breaks are built into the tour.
After the tour, I made all of my fastpasses for AK (Expedition Everest, Kali River Rapids, and Rivers of Light), so I can get all of the "thrill" rides done in one day. I had rode Dinosaur earlier in ym trip, so i didn't see the point to ride that again.
------------------
The tour got more worth it as the day went on in my opinion. A lot of the rides at MK that we went on to start would have been walk-ons or a short wait. The attractions I found it worth it at MK would have been 7DMT and Pirates (40 minutes when we got there). The reason why i say this is the day before, I was able to ride Space Mountain, Splash Mountain, and Big Thunder Railroad in the first hour of MK being open. Haunted Mansion didn't have a wait when i got there. When we got to Soarin, it was a 55 minute wait. After that, Hollywood Studios had the longest wait times. Rock N' Rollercoaster was 75 minutes, Tower of Terror was 60 minutes, Toy Story was 60 minutes, and Star Tours was 35 minutes. I find this service basically to be paying for time. You go in the fastpass line for each of these attractions.
I still don't see the point to go to EPCOT only to ride one ride. This is the Ultimate Day of Thrills Tour, and you won't even go on the ride that posts 64.9 mph (Test Track)!!! I would easily get rid of Haunted Mansion, Star Tours, or Toy Story and change that with Test Track. That is since those aren't really "thrill" rides in my eyes. A better lunch location would be nice too. We are in EPCOT with a lot of food locations that I find to be better than Sunshine Seasons.
Is it worth the money? I would say yes. Is it a great experience? I would say yes. I only wish that Disney could make it just one hour longer, and take advantage of going to Test Track and possibly even Frozen.
I hope everyone enjoyed reading my review!

I know it is probably just a pipe dream, but that would be so cool, I can't help but wish for it. I will do my best to keep my expectations in check.
