Kansas to Manhatten? Dang. Talk about culture shock. There is a CG in NJ on the shore you can see Manhatten from. Stay there, take alternate trans into the city.
I have very little experience with Manhatten, That was about the extent of my knowledge. Been there, didn't like te t-shirt.
I don't remember the name of the CG, but you should be able to find it in one of the directories.

Walmart overnights. I would do them while travling, our only experience to date was back in RI. CG we wanted to go to was full, but would be available the next morning. We stayed in their overflow till about 9PM, moved to Walmart and went back at 6AM for our line spot. However, that overnite was trying. There were some kids there about 1AM playing car alarm soccer. Kick a goal, hit the car set off the arlarm. reset, replay. Couple hundred feet from us, but dang!
