We picked Green Meadow due to it's proximity to Story Land. Didn't realize it's literally right next door... We could have walked if we weren't lazy. Worked great, going in the afternoon one day and getting free passes the following day. So we got to hit all the rides as much as we wanted. 

Also close by to other activities like Cranmore Mountain (cool summer activities for kids), and North Conway. 

Being so close to the park, we DID have a lot of noise from the park. Rollercoaster and sound effects could be heard all day long, which is fine since we like to be out and about. Noise shut down early, with the park, so zero issues overnight. 

Everyone we ran into was pleasant, and evenings had scores of kids riding bikes and having fun around the playground. Very family friendly.
