Even with TT, we haven’t found G+ that useful for Epcot and I expect that’s the same with Multipass. Without a child in the group, we haven’t ridden Frozen in years. It’s nicely done, but like Peter Pan or 7DMT is not “worth” an hour wait. We’ve done G+ on two of our 3 most recent trips, but really only got value out of it by hopping to Hollywood.
On our last trip we didn’t bother. After our Guardians VQ, I single ridered TT while she shopped, and we waited for Soarin’ and Remy at opportune times. Remy is probably a one and done for us. A bunch of screens on a ride isn’t our thing, though i am glad we tried it. Walked back around to some food booths and World Showcase shops, and had some fun on Three Caballeros!
