I thought it was nice.
Didn't quite appreciate the ripping on New Jersey >_> gosh, why everybody be hatin' on the Joise. I do find ripping amusing, but at times I'm like, seriously? Commenting about smog when they're flying in from New York. But eh whatever, it made me chuckle a little.
I liked the ending, Peridot has just been amazing this Season. "My home away from Homeworld". Also, we get to see how much taller Lapis is to Peridot. Peridot comes to her hips it seems. Looks like all the fanart of them being the same size now is kinda retconned haha.
Overall I think it was a sweet episode, and had a lot of nice sentiment to it. It was rather slow, but I enjoyed it
