It's been a good 8 yrs since I've been back to Manhattan, but I believe there is a Holidome on the hwy going into Manhattan from the west. Would be less "traffic" getting to JC. The hotels aren't bad, but nothing great.
Nice thing about the Holidome is that it's out of the "busy" area and easy to get to JC, mall, downtown. Closer to airport also.
Glad to here he's comming home. Be sure to tell him we say "THANK YOU" and we are proud of him. God bless them all.
I can do some calling for you if you'd like. I'll set you up how you want and do my best to get a great discount, I was in hotel/rest mgmt there.

Email me and I'd be glad to help,

Use me if you can/want.
