I'm looking in this area for a number of reasons. I'm driving up in my own car and prefer a hotel with free parking. Having lived in Jersey City a few years ago I'm familiar with the area. And like you mentioned it's a less expensive alternative to staying in Manhattan.
Here is the amenities list from the Hotwire Easy View tab, which seems to be identical to the list I posted above.
FULL AMENITIES: Pet friendly, Near beach, Indoor pool(s), Airport shuttle, Smoke-free rooms, Fitness center, Pool(s), Restaurant(s), Business center, Internet access
