Hoppers enjoy the low crowd early park closings without sacrificing nite shows and hours. Not cheap and by no means necessary but since they came with a decent food package that did save us money, we'll take advantage.
For MK party season we can do a low-crowd 6pm MK closing and hop elsewhere that night, and we'll also enjoy the nite EMH and fireworks at MK after visiting AK with a 6pm closing that day. Hoppers definitely help us navigate our schedule around the lowest crowds.
